That episode was kind of stupid. You literally have two helicopters and know that everyone is together. Yet, you do not bother having one in the air looking on the roads to see if people might be coming. In reality you could have trapped the ambush just by setting all that up, to have them drive right into an ambush.
Also,
How hard is it to hit people barely running in an open field towards a helicopter in such a way that if you missed them, you have a descent chance of taking out the helicopter.
That episode just felt off.
