What LT. Col fought in an famous battle in Vietnam?

LTC Hal Moore fought his battalion at the Ia Drang in '65. The film "We Were Soldiers Once...And Young" (the full title of the book) was his story.

However, ALL US Army ground battalions (and probably all US Marine ground battalions) were commanded by LTCs or promotable Majors.

A Rifle Company (Infantry Company) was commanded by a CPT or a promotable 1LT (1st Lieutenant).

Another Words, they're all famous (if they've been blooded in battle); it's just that some have books written about them or films made about them. And some don't.
