Yea, but then you would be nearby when a few dozen pissed off Marines jump off the other trucks in the convoy. Plus air support, tanks etc. The last thing insurgents want to do is be anywhere near the actual fight.
You'd be nearby looking like every other civilian.
And very few shots are fired during an IED strike unless there is the accompanying ambush (That does happen occasionally) inbound. Even Marines don't shoot randomly at things.
SOP on an IDE strike is to secure the area and evac the wounded. That won't involve shooting unless there is reason too.
