A Ukrainian soldier holds a familiar RPG grenade launcher, but instead of the standard rocket, it's fitted with a mortar shell. The war between Russia and Ukraine, entering its third winter, has depleted ammunition supplies, forcing soldiers on both sides to seek unconventional solutions. One such tactic, long in use, is modifying the rear of 82-millimeter mortar shells. While not as effective or accurate as standard RPG warheads, these rounds serve as short-range artillery, allowing infantry to slightly increase their firepower.
