Gedis, whatever, I've already given up. I think this statement "Reactive armour is the evolutionary counter to the sabot round. Any nation that intends to use sabot against it is a nation of idiots," correctly sums up how uninformed baff is at armor combat. BTW, to everyone in the U.S., Western Europe, Canada, Australia and most of the Western world, Baff just called your nations a bunch of idiots. Gee, despite responding a MONTH after (I mean, you'd think he'd just drop it), the guy still has no idea what he's talking about.

Excellent. Looking forward to this release.

My script only works against RPGs (and anything that inherits from the RPG-class). I don't think slat armor "works" against anything else.

Of course, there are people like that on all forums. But I'm pretty sure Vasily Fofanov is a reliable source - he has more credentials than the combined sum of "experts" on most forums. From my understanding, the principle purpose of spaced armor is no longer to prematurely detonate HEAT rounds. Rather, it's effect (when combined with sloped armor, like in the Leo 2A6, Merkava) is to introduce forces that cause the penetrator to bend/tumble as it travels through different media (metal and air). Well, even if a lot of Strykers haven't been knocked by RPGs, you can't really attribute that to slat armor working as "spaced" armor. Slat armor is supposed to offer protection by crushing the nose of the incoming RPG and destroying its fuse, not by prematurely detonating the warhead. I'm not saying I'm right, just that IMO, I just don't think it's likely that slat armor would offer any significant, "extra" protection if the RPG somehow survives the slat cage and detonates. From the limited knowledge I have, the destructive effects of HEAT warheads depend on how much the "jet" is disrupted after it punches through the first layer of armor. If its composition is sufficiently screwed up by the armor (yet it still manages to punch through to the other side), it becomes extremely destructive and basically anyone on the other side is dead. However, if it's strong enough to punch cleanly through, then damage to the vehicle may be minimal, as the jet just punches through one side of the vehicle and exits out the other side, while still being a "jet." So you might have a really powerful HEAT warhead that will destroy a T-90 and kill everyone inside, but then use the same weapon against a M113 and you'll simply make 2 nice holes on either side of the vehicle. That's my understanding on the after effects of HEAT penetration anyway. Probably talking out of my ass.

No, if you want, I can definitely cook up something for you. The thing is though, there's basically no difference between a detonation on the skin of the Stryker or the feet or two outside the slat armor. The HEAT jet retains its penetration for a couple metres - so in reality, I really don't think that slat armor can work in a "spaced" armor type fashion. See this thread on Tanknet about spaced armor: http://63.99.108.76/forums....d+armor "There is much more serious problem with spacing than volume. It is the fact that it has a really minimal effect on modern rounds. You need the spacing of meters to seriously disrupt a jet. In the tests modern HEAT charges impact on one side of thetarget tank and exit from another. I.e. the entire tank interior acts as spacing and this still doesn't protect the opposite side from penetration." - Vasily Fofanov If you want, I'll see if I can get something going on tomorrow.

Good assumption I used something small - I think it was like 10 hit and 5 indirect hit. The main thing was I just wanted the RPG hit effect (it looks funny if you simply delete the incoming RPG round). But by all means, if you have something better, go with it.

Finished the script. It's based on other people's work, as I'm still somewhat new to the OFP scripting game. In the Stryker's config file, add this line to EventHandlers: IncomingMissile = "if ((_this select 0)==(_this select 0)) then {[_this] exec ""\Stryker*\Scripts*\SlatArmor.sqs""}"; (the italicized portion is changeable - it's merely just the folder/PBO path) The actual (beta) script - if you guys wanna incorporate it into your add-on, just save it as an SQS file and link to it in the Stryker config: "RPGslat" is basically a weapon I made up and incorporated into the Stryker config. It's the same as the BIS RPG in every way except that it does less damage. The script randomly runs 60% of the time whenever it is called - thus, the slat armor would protect the Stryker 60% of the time against incoming RPGs. If it passes the 60%, it looks at the incoming missile, checks if it's an RPG (or if it inherits from the RPG in the CfgWeapons class) and deletes the incoming RPG and replaces it with a weaker weapon that does no damage to the Stryker.

I think I'm actually going to script the whole RPG vs. Stryker thing. IRL, the slat armor isn't actual "armor" that protects the Stryker (in the same way the addition of more steel plates/ERA/ceramic tiles would help increase protection). The slat armor basically crushes/destroys the fuse on RPG weapons, stopping it from detonating completely, and in reality, is only about 50% effective. So I was thinking of a script that checks any incoming missile-type weapons to see if they're standard RPGs and just basically stop them from detonating 50% of the time. If an RPG does successfully detonate its HEAT warhead, it's gonna knock out its Stryker target, slat armor or not.

Since when did the German and the French use the same gun/ammo? The French Leclerc uses CN120-26 120mm smoothbore cannon, firing customized French rounds. The Canadians only recently bought surplus Leo 2s, and only a handful of them were of the 2A6 type (with L55 guns). Thus, your statement is incorrect because none of the countries you listed used exactly the same gun or the same type of ammunition. What? HESH rounds typically have extremely slow muzzle velocities - something on the order of sub-1000m/s, IIRC. If you're gonna be firing HESH rounds, what's the point of upgrading to an L55 gun? Your HESH rounds don't even need all that extra muzzle velocity. If the Brits upgraded their Chally 2s with L55 cannon just to shoot HESH rounds, then that's a waste of money. Nobody else in the world uses HESH rounds to attack T80/90 threats. Just a thought - but perhaps you got it wrong, and people don't actually use HESH rounds to attack frontline MBTs?

Civilians that actually make a living in such engineering practices. Obviously, it's still public information so should taken with a grain of salt, but it's the best data we've got to go on. If you got a military source that says the DM63/L55 achieves better penetrance than the M829A3/L44, I'd love to see it. Very likely. The behavior of the penetrator with the armour it's penetrating is everything. Factors like muzzle velocity are simply factors that deliver the SABOT round on target so that when it does hit, the conditions are favorable for penetration. Yes, in most KE cases, especially regarding non-DU munitions, extra energy is good for the rod. But if your KE round destabilizes a bit in flight due to higher velocities, it might experience forces/conditions that negatively affect the KE rod once it hits its target. If the conditions are bad, the penetrator rod might not achieve maximum penetration, or it might even break up. Faster is not always better. It's a good general rule, but there are obviously exceptions. Take the M829A2 vs. the M829A3 for example - despite being a generation newer, the A3 is 100 m/s slower. Or even better, which would you expect to withstand the shearing that K5 ERA uses to defeat APFSDS penetrators: a thinner, lighter, faster DM63? Or a heavier, thicker M829A3? You're probably right. But I'm not talking about just the Brits here. Just because the L55 worked out for them doesn't mean it would work out for everyone.

Less capable? You're basing this on the one, single parameter where the L55 gun can impart greater energy onto its KE rounds? There are obviously many more factors at play For example, there have been concerns that upgrading the M1 Abrams with an L55 gun would negatively affect the M829A3 penetrator (IIRC, it was something about high velocities screwing with its flight). Furthermore, depleted uranium isn't like tungsten, it doesn't draw as much an increase in penetration with increasing velocity. And even if we neglect all this, it is widely accepted publically that the L44/M829A3 combination still punches through more armor than a L55 gun shooting any APFSDS round, despite the KE energy advantage of rounds being shot out of an L55. Yes, the L55 does lob DM63 rounds with 12.5% greater muzzle velocity, or about 26% more energy. But it's shooting a smaller round faster - the DM63 is 25% shorter, 14% less thick and 40% lighter than the M829A3, for the advantage of less than 200m/s increase in velocity (1750 m/s vs 1555 m/s). These characteristics of the APFSDS rounds are important, "other" factors in defeating that T-80 with K-5 armor.

Great, thanks a lot. BTW, does the Stryker still get blasted 60 ft into the air when hit with an RPG?

Solus, awesome mod, but is there anyway to change the helicopter AI so they don't fly straight into the the clutches of a waiting Shilka?

Only really old heat-seeking missiles are limited to engaging targets from the rear aspect. The Stinger definitely does not fall under that category.

Good post, cept for this part. You got it reversed - the AIM-54 Phoenix uses a combination of SARH and active radar homing (the latter for the end-game). On the other hand, the AMRAAM guides by active radar homing (in the end-game) only - thus, it will only trip the target's RWR when it turns on its own radar several seconds before impact. Furthermore, only the earliest versions of Sparrow were beam riders - all Sparrows from the AIM-7F on-ward (circa 1970s) are SARH. IIRC, the latest Block II Stinger RMP missile uses an FPA-type seeker, like the AIM-9X.
