Men of war recon/ need some help.

[RHYS4190]

Hi guy's I know how to do mapping and the first mission of my map IS DONE just need a few questions answered and it will be released.

im planing on making a series of small missions. iv made the first mission is a probe into enemy defenses objectives are to destroy two AA batteries guarding a major red army supply hub. with the main objective being making it seem like a major attack and getting the Russian to mobalise there reserve out of hiding in order to ascertain there numbers. mission will end when you got all your troops back at there starting point.

Made every thing iv got the guard force established maps done. but the problem is getting the Russian reserve to mobalise there troops once the player has lit up the two AA guns.

My question is very specific in my missions there will be no reserve forces that you can call upon but i do need to know how to make these triggers.
