After patch 1.18 OPFOR autonomous static weapons (o_hmg_01_a_f and o_gmg_01_a_f) become, after being disassembled, BLUFOR backpacks (b_hmg_01_a_weapon_f and b_gmg_01_a_weapon_f) instead of OPFOR backpacks (O_hmg_01_a_weapon_f and O_gmg_01_a_weapon_f).
This issue can affect scripts that are used to control number of static weapons or disassembled static weapons (backpacks) since they cannot count the number of disassembled OPFOR static weapons that are on the map.
