Helos are not resilient; I have seen the routed from ground fire, MANPADs, AA, and SAMs far more than I have seen them do anything practical.

The AI loves to shoot at them the second it gets LOS to them and won't stop until you, as the player, break that LOS.

I would say that someone is trying to use their helos as tanks, not as what they are flying targets that draw attention the second they get above the treetops.
