As an armour main, I quite like the updated damage model in this mod. It's a lot more fun and even somewhat more realistic than Vanilla's damage model. However, vehicles still do feel too "tanky". The only way to kill them is an ammorack shot, fires (AFAIK) only harm crew members.

My suggestion is to make it so that a fire slowly drains the HP of the ammorack, so hitting a fuel tank and causing a fire should lead to a vehicle exploding UNLESS the fire is extinguished.
