Medevac system

[davidoss 552]

Hi.

I am working on medevac system where players would have an possibility to call for medevac helicopter.

The med heli have AI crew and doc.

 

 

What i am thinking of is

 

• what is the best scenario situation to call medevac call for one wounded or maybe if more
• medics should have the chance to revive wounded only if wounds are not on head or chest (heavy wounded)
• if heavy wounded there should by only stabilize and call for medevac action avaible.
• who should do that ? medic maybe?group  leader?
• after medevac arrives wounded will be dragged  into heli and transported to medic center.
• medic center crew  heals wounded after some time while laying on OP table. (Voices and animations)
• should that be avaible for any unit or players only?

Any suggestions would be amazing.

cool man...

 

I was going to pick away at this idea at some point too

 

 

-would be cool if the injury defined whether the incoming medevac healed or transported the downed player\ai. maybe by returning the hitpart .

- personally  i would limit it to players and grouped ai, but thats just me.

-medic can stabilize and group leader can radio for medevac

-option for full medevac or simulated medevac, meaning for mission purposes full transport back with voices anims or just heli disappears and reappears with delay for using while in mission. no point in simulation of stuff players will not see.

 

just some ideas..

looking forward to see where it goes

Really like the idea!!!  particularly cool is the idea of the player seeing the medic center / doctors taking care of him when heavy wounded. Although it may seam not needed or  a waste of playing time, let me give you an example.....

 

When I was playing the first (best IMHO) version of America's Army there was a "Jail time" if you did a teamkill. You where "stuck" in jail without being able to respawn or get back to lobby. So I wouldn't mind to "see" the medic taking care of wounded..to be able to respawn back to the squad after a certain amount of time.

 

So,in a perfect "world" I think that what I would like to have is:

 

-light wounds(limbs)=  squad medic can patch you up and you continue with mission.

 

-heavy wounds(chest with armor/abdomen)= squad medic can stabilize you/AI, but you cant fight and need to be medevac

 

-critical condition (head/chest with no armor)= mandatory medevac with 50/50 to "make it" or die on the surgeon table.

 

I would like to see this only for players (the medic center part)..Ai will be medevac..and respaw back to squad as patched up or replacement....

 

Just my 2( :P ) cent...

[teddymosart1 40]

I would like the wounded Ai to be patched up and then re-inserted by simply dropping him from a parachute....I would suggest that someone build upon Fulton recovery mod by adding a stretcher and a plane.

or

if someone coperate with all things that they can think of and make a mod of it.That would be soo cool.

Great idea. I was wondering about this a week or so ago.

Tbh, I'd like to see medics stabilize and team leader call in evac, once help lands at safe lz with smoke, the player/s have to carry to chopper where medic is on board, then transports to fob or medic base to revive. Maybe make players wait so many minutes and that could be varying based on mission maker choice. Say 5 minutes. Then to be reinserted to team has to take transport back to squad. For me it's about having players be more aware and avoid silly situations of getting downed if possible ie Rambo tactics.

Awesome to see you on the job! Good luck!

[barbuse 5]

Great idea !

I think the best way would be that the medic can stabilize the wounded and then team leader calls the medevac.

If you want to have a realistic medevac then in real life it usually works like this:

• one soldier is wounded so his team/group put him into cover and stabilize him then carry on the mission
• then when possible or when too many wounded, one group would be charged to get all the wounded back together in a casevac zone that has been secured
• finally they would be evacuated

So maybe you could use a revive system as we see in domination or CTI missions and then when you're down the team medic can come and stabilize you but you still cannot fight until you're evacuated and allowed to come back. Also when you're down, if you're not dragged into cover and get shot again you would die.

Hope this helps ! Good luck :)

I've been thinking on this for months, lol. Glad someone posted so I could share my thoughts.

Right off the bat, consider making this compatible with ACE, as they already have an extensive and very impressive medical system in place. Using ACE, you can easily designate the helicopter as a medical vehicle, which when near the group would promote non-medics to medic and medics to Doctor. You can choose in the settings what the 3 levels of training do.

For the procedure, I'd let anyone call the medevac, and take them through a simplified 9-line using actions as prompts (like calling artillery). The medevac would then be able to launch with the required composition because they'd know:

1. how many birds to send based on how many casualties of what type were being picked up.

2. Whether or not to send an escort bird if it was a hot LZ, etc.

3. Whether or not they should bring a winch (had an idea to be able to winch up patients but a system would take time).

4. what kind of LZ marker to look for.

When the medevac gets close, have the players mark the LZ with whatever method they stated they would use in the nine line. Similar to vanilla pilot can confirm the smoke color or whatever, then set down at the nearest good spot. Smoke or any kind of marker can also be used to create an invisible helipad, which helps the AI land.

Once the AI lands have the players drag and load any WIA/KIA to the bird in order of precedence. Once an unconscious patient is on the bird they're stable and can be fixed by a player on site or, upon landing at base will be fully healed. They can then catch a transport back out or whatever. Conscious patients could load up to get fully healed or to simply catch a ride.

As far as the "benefits", this is difficult since medics already have such a small role in ArmA. But I think I figured out a few, esp for Multiplayer.

1. If a player is unconscious (or in revive state), a nearby medevac bird will increase the time they remain in that state. In other words if they make it onto the bird they're likely to survive.

2. Can act as a more realistic form of garbage collection. Place the dead in body bags and place them on the medevac bird and their bodies are gone. Could also implement this with pulling dog tags.

3. Can integrate with respawn. For example a player could only respawn once their body is handled. Can also serve as a transport back to the AO for previously killed players.

4. Can provide resupply. Load the medevac bird with useful stuff like medical supplies to and some ammo for the guys in the field. A group with casualties will need this. Maybe change the loadout based on the enemy around the calling group. If they're facing armor, give them AT stuff. Can integrate this with the 9 line as one of the lines is special equipment.

5. Can provide limited CAS by putting some mini guns on that beast and giving it an attack helo for escort.

6. Can reduce penalties according to game type. For example if a KIA is loaded onto a medevac, the side doesn't lose tickets for that respawn.

7. If using advanced medical, give the helicopter a PAK style action that any player can use to heal all their wounds. This gives groups playing without a dedicated medic or with tough realistic rules a way to replenish blood, close old wounds, and get rid of annoying stuff like a limp and pain level without having to RTB.

8. Place a diary entry or map marker for persistent or long running servers, allowing JIP players to see what happened before they jumped in, gives them an idea of the hottest areas.

9. Let the medevac bird serve as an arsenal or loadout manager, giving the players the option to change their class and equipment. Maybe make multiple tiers of this so its not too OP.

Do medical helicopters actually fly in and patch soldiers up and get them back in the fight? I was always under the impression medevac meant exactly that: Medical Evacuation. So I could see it being used to extract incapacitated units with significant wounds, but if someone was hit in the arm or leg and it wasn't critical I figured the medic would just patch them up if they could stay in the fight and then maybe extract them later when the AO isn't hot if necessary.

 

But I've never been in the military, so for all I know I'm wrong.

[M. Buchanan 21]

Well... No. I'll preface this by telling you I was a medic for ten years just so I have SOME credibility here as a new poster... That said... In real life medevac birds consist of a pilot and co-pilot and one or two flight medics in the back. They're very GOOD medics, but they aren't doctors. They'll keep you alive long enough to reach the nearest surgical team or support hospital. 99% of the time if you make it to a bird, you make it home.

As far as injuries, anyone who's been shot is pretty much guaranteed a ride out these days, minor or not. This is the case for conventional forces that can call in medevac. This is true whether it's your arm or your face, whether you're incapacitated or not. Only in extremis would we leave a wounded man on the ground and continue mission. Special Operations has their own unique situations and medevac doesn't really apply the same way.

My thought about using it as a treatment platform is that, well, with respawn there really isn't much need for true medevac. Most groups would find it a major hassle, and it's no fun for the wounded party. However if medevac allowed them to stay in the field longer and do more without returning to base, and fixed people who usually couldn't be fixed out there... Players might find that fairly useful.

I suggested this idea to the large unit I play with and to the ACE team, putting it the way you describe (realistic medevac), and pretty much got shooed out of the room because it takes away from the experience, in their opinions. Not for the medic of course, but who cares about us!? Lol

[davidoss 552]

Thanks for reply guys. Much appreciated.

 

The problems of making it usable in gameplay

(which you guys brilliantly pointed out)

are the biggest i am struggling with.

 

We all looking for  realistic battle in front line but nobody cares about behind lines.

This is only a game but,

i would love to see behind scenes of current fight near the base  when i JIP

[soolie 189]

Really like this idea and have messed around with it a lil on my own. Good luck! Lmk if you need a UI for it. Would be happy to make one up for you.

Some of the UI's I've done.

This looks great! Maybe,use some stuff kind of like Fulton Recovery mod?  Like a Hoist?  Don`t copy and paste ,tho`...ask if you could use something like that,from there in.Just a suggestion.

 

Armed escort may need it`s own kind of Waypoint.  A +1 if this could be made to work in Arma 3 for me.Good luck!

In ArmA2 I created an automated MedEvac system, where AI could be called when someone was wounded. Unfortunately I lost the code for it, but this is (roughly) how it was set up:

 

1) On a designated base there was a helipad and a hospital tent, and of course a fully crewed helicopter (AI)

2) If a player got badly wounded, the medic would have an extra scroll action "Request MedEvac"

3) The helicopter would take off and report an ETA (based on distance) and it would fly towards the request (random spot in a 100 meter radius)

4) When the helicopter was in 300 meter range, it would request a smoke signal by the medic

5) The medic now would have to throw a smoke which would be the landing area (within 20 meter radius)

5b) If no smoke was thrown, or too late, the helicopter would fly around at a 50 meter radius of the original spot (see point 3) till a smoke round was thrown by the medic

6) After the helicopter was landed, you needed to put the wounded in the heli

7) 30 seconds after the last wounded it would take off, and fly back to base

8) Back at base, the wounded player(s) would respawn into the hospital fully healed

 

 

Of course it's way more fun to have real players taking the role of MedEvac (minimum of 1 pilot, 1 crew and 1 medic), but that's another topic ;)

this is more like i was thinking too.

 

Farooqs revive allows medics to stabilize perhaps you could consider / look at how his does that to stablize a player, 

 

https://forums.bistudio.com/topic/146926-farooqs-revive/

 

Psychos revive allows to pick up players, same thing

 

https://forums.bistudio.com/topic/161291-a3-wounding-system/

 

TBO, i would just consider making a medic revive system incorporating the medic evac, i am sure ACE would be a cool thing along with it, not sure the complexity,

 

also, i think one of the biggest hurdles is having the stupid AI heli land nearby enemy AI / distance from seen enemy, i know people have had issues with AI pilots doing what they are told, per sae.

 

Anyways, hopefully this helps, i do not have the skills to script but if i can assist any other way just shout.

 

good luck!

[davidoss 552]

Thanks for clues guys. Much appreciated and looking for more.
 
For now i focusing at vanilla revive, maybe after i would be able to add some selectable usage of our great community revive systems.
 
By now i have selectable medcenter positions, helicopter model and who can call it.
 

amsc_marker = "medcenter"; //select your marker where the medcenter is gonna be
amsc_medheli = "GR_UH1H_4"; // select your desired heli classname
amsc_requester = 1; //select who can request medevac 0 - medic, 1- team leader, -1 both

Here some feedback video whats are done already
Its very basic for now in compare whats are running in my imagination.

[MFG4Ever 13]

Very nicely done!

 

One minor suggestion, if possible, have the helo's engine running when on the ground at the evac site.

[davidoss 552]

Good catch thanks it should looks like indeed.

[jandrews 116]

Nice so far. Look forward to seeing the progress on this. Looks like maybe a mod? Are you thinking of a new medic revive system altogether?

I forget how the default Arma revive works now. Does it work? Are you thinking stabilize in field and full health at base?

[davidoss 552]

Calling medevac will be forced by:

For example:

Lets say we have couple of injured soldiers in our team.

Some of them can be healed by  field medic but according to highest damage there will be someone with respawn disabled and

action stabilize visible.

if (medic is ok or leader is ok )

Person doing stabilize action says something like   "You gonna be alright dude" and than quietly "oooh whats a mess."

Reports trough radio like "Hey chief we need medevec here".

chief or medic calls medevac

medevac will be initialized

 

else

 

respawn will be enabled  again for stabilized player.

 

When medevac arrives and count players waiting for evac > 1

medevac medic check the injured stage (animation) and randomely  (yes or no) will heal someone in place saying something like "whats a morans"

otherwise he will drag player/s into heli, jump in and reports something like "ok lets go we done here"

 

 

If whole group are vanish for example by car explosion

there will be radio chat from crossroad calling up the group.

After few tries crosroad will send medevac automatically if avaible.

 

Thats for the field part

[supergruntsb78 67]

i remember this   http://www.armaholic.com/page.php?id=9557    now that was a awesome medevac system,  perhaps you can find inspiration from it ?  

[teamwolf 20]

We have been using a coop map called Medevac for Arma Flight School every Thursday night for students to get real world flight time and training. We are getting a pretty good size group playing and now have expanded to two Blackhawks full crew with 2 PJ's and now were adding a gun ship. Everything is planned out to the wire. As you can see here. https://docs.google.com/presentation/d/1qbhCBez4Oe83WSpK55OxlW95WNo38ZCzptWWRsA9IA8/edit?usp=sharing This is the document we go through at the start of every class. We try and rotate so everyone has stick time except our JTAC and PJ's.  

[davidoss 552]

Woow thanks, this will be helpful.

[patapes 0]

That would be awesome! 

[avibird 1 155]

Hey Davidoss this is Avibird 1 lost my account since last update to forum. 

 

This is something that I've been trying to get working for a long time. The ability to drag carry and load wounded units independent or Incorporated with different revive scripts. 

 

Functions that would be great to have.

 

1. The ability to set the bleedout time to die and the ability to keep the wounded unit in the incapacitated status until revived or all the playable units/players are incapacitated which then the mission will  end.

 

2. The ability to set the wounded system for players playable unit aand for what side blufor opfor ind civ.

 

3. The ability to set medevac vehicles to land sea or air vehicles.

 

4. The ability to set the number of times used and the  time to recall the medvac vehicles

 

5. The ability to load the wounded units in other vehicles just in case the medvac chopper/vehicles are destroyed.

 

This is something that the injury systems that should have been in the default vanilla game for sure. 

 

Let me know what you think. I would love to test your work if you need testers.
