He said the Thompson was great but need cleaning all the time, the carbine was a beautiful weapon that needed constant cleaning and had terrible stopping power past 50 yards. The grease gun was durable, NEVER needed cleaning and had good stopping power. He said he nailed a ChiCom radio operator behind a thick wooden door at 75 yards. The operator was wounded but the radio did not survive.....
I finally realized that a loaded M-14 weighed the same as a grease gun and was much more effective at all ranges, so I traded the grease gun to the SeaBees for beer.
Carried an M2 Carbine for a short while too - an excellent, controllable full-auto weapon but all I used it for was killing a crocodile we spotted in a river. As before, when your life depended on it, the M-14 was the only choice.
