Most of my first enlistment was spent with either a 1911A1 in leather flap holster or M9 in a Bianchi hanging from my LCE with an M60 in my arms.
I was lucky, I had a Litton instead of a PVS-4. This was the era when maybe one person had PVS-5s per squad for part time use.
The M60 was like a Harely of the era. It required a significant amount maintenance to keep in top running order. And gunner skill.
There are some inherent aspects to the design, that like the M9, keep it from certain steps for modernization and improvement. Like the 1911, it is prone to much more effort to keep reliable in harsh conditions in comparison to some other options.
When I was stuck on a Bn Staff at 7th Group as a newer Captain, after heavy range days I was unaware that part of the current command elements hazing was giving the 60 to the new guy to clean. I had just signed in prior to the major range week. (The command and staff element together cleaned the crew served weapons everyone had used as a group instead of making their personnel do it)
They were shocked to seem me break it down, to include feed tray cover, bolt, etc. when I asked the armored for a new extractor because of a stress fracture I found I was informed the gun had been down and neither the armored or some 18Bs had figured out was up. (It was a very subtle finding, but the exact reason for all the FTEs)
The BC, XO, S3, CSM, Company Commaders and SGMs all had serious WTF expressions. Being a former Ranger BN 60 Gunner, and also a Weapons Squad leader in a NG Infantry unit that ran the Bn’s 60 ranges each summer AT, plus shot the 60 for state AG matches when I went to college had set me up for a fortuitous coincidence that made a hell of a first impression.
Despite its flaws, and the fact that it was replaced, I would still feel a little wistful heading out on target with the Rangers with their modernized FN MAGs.
And, despite its flaws, if they were priced more like 10K I would buy one, back fill a buttpack on a GP strap with five belts, and live like a king.
