I'd heard the name Basil Plumley in passing somewhere before;

wish I'd thought to look it up then.
The men of the 7th Cavalry held out valiantly, but ultimately they were still outnumbered five-to-one, deep in enemy territory, and completely surrounded by troops with heavy weapons pointed right at them, and casualties were piling up. But Plumley didn't give a shit. He wasn't about to fucking back down. The unit's commanding officer, Hal Moore, vividly recalls in his book We Were Soldiers Once… and Young that he was standing there with Plumley, looking at the piles of wounded and the untenable position they were in, and he was like, "Jesus Christ, it's Little Bighorn all over again!"

Plumely just looked at him, no emotion at all, and said, "Custer was a pussy. You ain't."

That night, as AK-47 fire ripped up the jungle, the order went down the American battle line – fix bayonets. When some of the troops were like, "what the fuck is a bayonet?", Plumley got pissed. Screaming over the din of mortars and machine guns, Plumley drew his pistol and said something to the effect of "You sons of bitches, take that pointy fucking thing you use to open your c-rations, stick it to the end of your rifle, and follow me!"
That's one part of his story.  he and Moore were well matched, and the enemy was kind of screwed.
