In 1898 the U.S Armed Forces carried .38 revolver .38 caliber is .357 9 mm is .355 During the Spanish-American war the .38 caliber proved insufficient to stop Islamic terrorists in the Philippines .45 caliber ACP was chosen, Browning designed a sidearm to stop Islamic Terrorists. It seems that DoD has forgotten one hundred years of history. The 1911 pistol may be 100 years old, but stopping Islamic Terrorists has remained the same. OBTW; Think of this question : is Islamic Terrorist redundant ?Does no one remember September 11, 2001 when America was attacked by Islamic terrorists?
Yes. There have, from time to time, been Communist terrorists, National Socialist terrorists, and various terrorists involved with nationalist movements that are/were not particularly ideological.
