Hello, I suggest adding the following things to the game:
The Security Commander can summon 1 armored personnel carrier with a machine gun (300 rounds maximum). Drops from a helicopter to a specified point. This will justify the presence of anti-tank mines. To destroy APC you need 2 hits from the RPG or 1 hits by land mine.
The Insurgent Commander can call 1 drone with drop 3 health kits to the points (for 3 allies).
Add medics to the game who can see the approximate health state of allies and can heal them for a certain time.
