When an IED disables a vehicle in the convoy, I jump out to assist. This is wrong. Unless my help is needed, an up-armored humvee is the best place for a fire team leader.
When I jump out, I’m in a hurry and forget to close the door behind me. This is wrong, as it leaves the other occupants exposed.
When I take fire, I fire back. This is wrong, as it is the turret gunners’ job. (Those bits in generation kill that show the humvee crews firing M4s from the windows is, evidently, teevee creativity.) If I leave the humvee, my job is to get on the “cold” side of the vehicle and assist with the crossload. I should only use my M4 to engage anybody who makes it too close for the turret gunners to shoot safely.
It’s very difficult for a vehicle commander to assess anything happening behind him. He has no rear visibility. He relies entirely on information passed over the radio and from the turret gunner. These are hard to hear at best and incoherent at worst.
All advantage lies with OPFOR. The determine the location of an attack and control the pace. They have surprise. They are impossible to see unless they fire, and difficult even then. Depending on the terrain, they can pop up one place, fire a burst, then duck down and appear somewhere else. Like wack-a-mole. Depending on the terrain, they face lots of easy targets, especially if they attack from both sides of the convoy.
All advantage lies with the blue force. Our up-armored humvees are (mostly) impervious to small arms fire. The .50cal in the turret can clear a forest in seconds. Depending on the terrain, a disabled humvee can be surrounded by the other convoy vehicles, protecting everyone during the crossload.
