The solution is simple slow down you probably paid the price by rushing those units back up instead of spending an extra turn to do it the safer way or didnt scout the area well enough in the first place.
Game wise you paid the price for your haste, real life you had best hope nobody realised it was you that gave the order cause you are going to have some mighty explaining & morale boosting to do.

Popping smoke works just fine its standard practice if you cant find somewhere safe to unload, smoke is a very powerful tool.
