Everybody always sends a helicopter probe. Almost every single game.
That probe will pay for your AA. If it cost 120 for whatever two copters they used, that will pay for three vetted AA missiles or nine flak.
Your alternative is to pay 200-300 for a command vehicle loss every game.
It's just stupid not to have AA at the very least.
If you use some heli transported infantry after unload you have your probe "for free". You can scout the area, these ~50 points are often well spend, because you can kill arty or unprotected command. I don't know why people still leave them unprotected.
The other thing is Kiowa Warrior. This heli is extremaly lethal due to excellent spotting range and very accurate guided missiles. It can fire at the command vehicle not being seen by the enemy, and because of Hellfire being ire&forget, quickly go for safety.
T-80U shoots AP rounds made of pure Communism... any more questions?
