Thank you for your service! I bet that grenade machine gun was a BLAST!
The Mk-19 is fun. IMO it’s forgiving even for a new gunner, and was a snap to clean.
The last year and a half I was with 2ACR, I was moved over to be an anti-armor section leader using the TOW. The TOW was fun (when they worked). But that was before the Regiment got raped by the infantry mafia.
