On Sunday we playtested my mate’s homebrew rules for moderns and near future, it was a refight of a previous game we had played and here is the AAR from it, will the Soviets get out of the Valley of Death? Find out here:
It happened often enough for riding on top of the BMP (rather than in it) to become doctrine. The problem is that, because BMPs are so small, the fuel is stored on the outside of the vehicle. They’re very combustible!
Not sure about the fuels stored outside thing. The S tank used diesel cans on the outside to reduce the impact of RPG rounds. The argument went and there were trials I rcall, was that if hit the vehicle could drive on and leave a flaming but harless (to the thank) puddle of burning fluid behined. Effectively the diesel works as a spaced plate. My reading of the RPG effect is that its damage is a function of its over penetration. In vietnam M113’s penetrated had the effect of about the same as a rifle bullet but they did not have a big overpenetration, much of the gass stream was used in penetrating.
The BMP rear doors are hollow and filled with diesel so the fuel is not ‘outside’ per se. Also the passengers sit back to back facing outward but the area between the two seat rows is the main fuel tank so the passenger compartment is surrounded and contains the fuel.
You can understand why the passengers might prefer to ride on the outside.
