M1A3 Grease Gun

The M1A3 grease gun was created by humans in 1942 as an alternative to the Thompson M1A1 during WW2 due to production costs being extremely high. Although the M1A3 was much cheaper and easier to manufacture, it had significant drawbacks that impacted its overall performance. One of these major issues was a slower rate of fire compared to the Thompson, which made it less effective in combat situations. Additionally, the M1A3 lacked the accuracy of the Thompson, resulting in a higher number of missed shots.
