In a Mail Call video, R. Lee Ermey answers a question from Carson a nine-year old boy from Colorado who asks when the Colt 45 started its service in the United States military and when it ended its career. The Colt 45 was invented by gun designer John Browning and made by the Colt firearm company and is one of the most famous military handguns of all time. The M-1911 had its official birthday on 1911 when the government was looking for a reliable man-stopper to replace the wimpy 38 caliber pistols that were in service. The Colt 45 became the weapon of choice for the U.S. Army, Navy, and the Marine Corps. In 1924, the 1911 was modified slightly and re-designated the 1911-A1. In 1983, the 45 automatic was retired after 72 years of loyal service.

In a Mail Call video, R. Lee Ermey answers a question from Tom of Kansas, who wants to know what the biggest gun in the world is. Ermey says to answer this question you first have to define what you mean by big; for we all know that guns like Big Bertha and Anzio Annie are big, but if you are talking total weight and size of the shell, then they are not the biggest. The Gustav gun created by the Germans, takes the cake on this one with an 80cm barrel. The Germans first used this gun in World War II; it was designed to pulverize French defensive bunkers in the early days of the war.
