The M18 57mm recoilless rifle started its design period in 1942 with its first test firing happening in October of 1943, when the M18 (then known as the T-15, made by Infantry section) proved to be better than its counterpart, which was concept from artillery section from the for a 105mm recoilless weapon.
The now known M18 recoilless rifle got aaccepted into service with the first 50 procuction pieces rushed to the front in Europe in March 1945, where it made its way to the 17th Airborne div. near Essen, to US forces in Po Valley in Italy and in Pacific where it was used in Battle of Okinawa, where it was praised as “pocket artillery” tahnks to its HE ammunition

Now I don’t know if to keep the M18 purely as AT weapon or if to also give it its already mentioned HE and Smoke shells as well.
However in Enlisted the M18 would have to use either the M307 or M307A1 which had the maximum penetration of 6in. ( 152,4mm) from 150 yards (137 meters) and the best part is that I managed to find declassified tests with pictures from Aberdeen proving ground, that are here for those, who want to read it.
I’d reserve that for AT Guns. Cannons are too heavy to be portable, so it makes sense you’d have to build them. Recoilless Rifles are portable, so a soldier can carry it into battle with no problem. Only a bunch of complaints. Lol
That is true but I have yet to see a picture of someone shooting an M20 from a shoulder since nobody ever did it (not even marines, which i’m kinda surprised). However, after a quick google search I found this:
While we are at it could you imagine if it got into Enlisted with the 2.8x side mounted scope? Wouldn’t that make the M18 the best sniper rifle in the game?
