To continue the FC2 trend I would sneak into an enemy encampment, plant IEDs under their vehicles and sneak back out. I would then get to a safe sniping position, set off the bombs and snipe them as they ran around like headless chickens.
Also in Mercenaries 2 I would attach C4 to whatever vehicle I was riding, get up to full speed then bail-out sending it flying into an enemy road block/encampment then detonate.
