Eh, 42 damage on average is very survivable. And it gets better from there.
I once had a hill the player force was assembling at prior to a Sally turn out to be a buried dropship. The effects were very medium.
Also had a fight where about 20 units got exposed to dropship exhaust twice at various ranges. Only 1 kill, mostly from the dropship guns, but if taking off was the final straw.
Heck, even trees often do fine...
