We already put anti-RPG screens around them to survive in Iraq (and they did quite well on the road-based fight). And now, in Afghanistan, we find that the light armor isn't survivable against the mines we face. So we're sending a "Stryker" brigade there with wheeled MRAPs:
The U.S. Army is sending a Stryker brigade to Afghanistan without their Stryker armored vehicles. Instead of their 19 ton Strykers, that carry 11 troops, they will be using 15 ton M-ATV armored trucks, which carry up to five troops each. The reason for this is that the M-ATV provides more protection from roadside bombs. While the brigade will have to operate more vehicles, they will have more firepower (each Stryker and M-RAP has a single remotely controlled machine-gun turret atop it).
Apparently, a squad will travel in two vehicles with a fire team in each.
