When we got there, we were told that to prevent attack, we needed to look like 'porcupines', namely have every rifle and their uncle sticking out the side of the vehicle. As a result, our SOP was that we'd have our armoured windows open, and rifles sticking out. I made a very quick assessment of the threat, and decided it was a stupid SOP, and ignored it, even taking flak from my CO over it:
"How are you going to shoot the enemy with the window closed?"
"I'd rather survive the IED intact first, sir"
I may be only an LT, but I like to think I'm a vaguely intelligent one.
Sure enough, we had some casualties in the task force from exactly what I feared might transpire: Troops riding with windows open and rifles sticking out windows, bomb goes off at the side of the road, fragmentation gets them in the face.
Similarly with the whole 'gunner popping up' business now. The most likely threat is not someone with an RPK or an RPG who you need to spot first. Neither, despite the publicity, is it a car bomb. It's the roadside bomb, and despite all exhortations to try to spot one ahead of time, more often than not, you won't and the first you'll know about an attack is when it blows up and pieces of bomb/shell go hurtling past/into your head. Since your vehicle is now likely armoured anyway and thus designed to stop fragmentation (from a 155mm round, in the case of an M1114) there's a much greater chance of defeating the enemy attack by 'cowering' instead of by standing proud.
For all the posturing above, the circumstances have changed between going around in unarmoured vehicles killing enthusiastic amateurs with direct fire weapons and the current situation of going around in armoured vehicles trying not to be killed by a more intelligent enemy (We've killed/captured the dumb ones by now) using asymmetrical weapons.
