M18 Recoilless Anti-Tank
The M18 Recoilless Anti-Tank weapon is a rocket launcher that is to be used against tanks, hence the name "Anti-tank." So far, it's only been featured in Battlefield: 1943.
 Battlefield: 1943
Found under the Infantry class of the United States Marine Corps in Battlefield: 1943, this is the heavy weapon used to knock out the pesky vehicles that are wreaking havoc. It takes multiple hits on a tank using it in order to destroy one. It has a small blast radius as well, so using it against ground troops isn't very effective.
