Best way to use airmobile and panzergrenadiers?

[Imp]

Very gamey but did this once as situation allowed.
Company of tanks & APCs about 20 vehicles making a run in the open to next cover which I was in a position to intercept just. Bit hit & miss on if my armour could destroy his tanks from the front so my helos swung round behind him drawing fire & turning around giving me targets which tanks engaged. Several Smoke dischargers went off so then drew fire with vehicles where possible then sent the helos the last bit landing directly behind a tank. Picked the ones that were covered by smoke & fired RPGs at point blank. Last few landed behind vehicles without cover but did not fire or took out troops.
What does he do now shoot at my tanks & recieve a hail of RPG fire to his rear or the reverse.
Lost a few airmobile units including a couple of helos while landed due to splash damage from own fire & the troops were smarting a bit but force was totaly wiped out. If he had unloaded a few more infantry or set more tanks not to opfire vs air it would have failed as they would have taken out my landing troops.
Forgot to mention they can be very handy in urban enviroments to though you have to be careful to follow the roads for cover. Drop passengers at delay postions or cut off exits. Helos can then risk attacking units you would otherwise have to move adjacent to. Can clear city blocks pretty fast this way then leave a couple of squads covering the road incase you missed one, once pretty sure helo nips back & picks them up or gives extra firepower if needed.
