The M136 AT4 Rocket Launcher is a Swedish-made single-shot 84mm unguided light anti-tank launcher. The company that designed this weapon, ‘Saab Bofors Dynamics’ is located in Karlskoga, Sweden and specializes in missile and anti-tank systems. The weapon was designed in 1984, and has an approximate length of 30 inches and weight of 15 lbs. It was adopted for use by the U.S. Army Corps as well as the Marine Corpse. The AT4 is designed to be single-use, and can not be reloaded due to its tube being specified to only be able to withstand one firing.
During the ACU ambush, a ACU operative fired a M136 AT4 Rocket Launcher at the Indominus rex. The Indominus was knocked over by the concussive force of the blast but got up almost immediately and escaped. A Rocket launcher was also utilized by an ACU operative to kill Charlie the Velociraptor.
