Trigger Help Needed

[CSM S. Ghering-1CD- 0]

Good morning and happy 4th for all us U.S. Members.

I am in need of some help. I am the MG (Master Gunner) for my unit and am designing Tank Gunnery Qualification Tables for my armored units. Basically what I need to do is be able to activate preset enemy tanks, APC's, Troops on a trigger that I can command.

What I want to do is setup 10 engagements, each on the radio. A would be 2 APC's and 2 sets of troops to spawn where I put them.

Question is how can I do this? I am learning the editor well but could use a "noobs layout" of how to do this.

Also, if done, can I have them "de-spawn" with the radio or do they just stay active until destroyed?
