The Russians have been bolting guns and mortars to various chassis to create unconventional vehicles. The latest is a BTR-D tractor with two 2B9 mortars, increasing its mobility and firepower. However, it is unclear if the compact BTR-D can support enough crew to operate both mortars simultaneously. These makeshift vehicles have improved over time, as the Russians gain experience in combat. They are adapting to their losses of purpose-made tanks and vehicles by utilizing whatever weapons and chassis they have available. [0187db32]
