August 24, 2012: The U.S. Marine Corps has ordered 12,000 .45 (11.4mm) caliber pistols (for $1,900 each), mainly for use by its SOCOM (Special Operations Command) and recon troops. These MARSOC (Marine Special Operations Command) troops have, like the army, navy, and air force components of SOCOM, quietly replaced most of their 9mm pistols with .45s. For the last few years the marines have been supplying their special operations troops with older M1911 model .45s, refurbished (or built from scrounged up parts) in a marine-run facility.

During the 1978 Joint Service Small Arms Program discussions about replacing the .45, it was really obvious that the Army had "cooked the books" to favor the Beretta 92 and its 9mm caliber. There were lots of theories why but my favorite was because "women had trouble handling the .45". (I never found that to be the case).

During the choreographed presentations at Aberdeen Proving Ground, the Army Colonel in charge asked if anyone had questions. I raised my hand and asked "if this the same 9mm caliber the Germans lost the last two wars with?" and was told to shut up and sit down.
