Long before the WW2 era Army decided to name everything the M1 (rifle, carbine, smg, helmet, etc), the Army used year of adoption as their naming convention.
This led to some pretty silly results, with many different types of gear sharing the same model designation.
I present to you the:
-m1917 Rifle
-m1917 Trench Knife
-m1917 Bolo Knife
-m1917 Helmet
-m1917 Bayonet
-m1917 Revolver (There were two revolvers, a S&W and a Colt variant both named m1917)
Not pictured are the m1917 Cartridge Belt, the m1917 Machine Gun, and a host of others.
While today’s system isn’t perfect (I.e. the M9 is both a pistol and a bayonet), it is a little less repetitive than the pre-ww1 system. But just to keep things wacky we’ve gone hog wild with acronyms. So instead of “Model 1983 Light Truck” we have the High Mobility Multipurpose Wheeled Vehicle (HMMWV), and instead of “Model 19XX Scout Optic” we have the Long Range Advanced Scout Surveillance System (LRAS3).
Damn it, bring back the year designations...

On this day in history, 19 October 1842, elements of the United States Navy and Marines heroically seized a fort in Monterey, CA (then a Mexican possession) from the Mexican defenders. There was only one blemish to this story... we weren't at war with Mexico and taking of the fort occurred as part of a misunderstanding!

On 08 October 1918, Corporal Alvin York of the 82nd Division performed arguably the greatest American feat of individual bravery during the First World War (another notable contender, and much less known, is Henry Johnson, AKA "Black Death" of the Harlem Hellfighters -- I'll write about that badass when I get the right relics).

The ACU is dead. Long live the ACU! It is now officially “military history” so I shall post about it: On this day in history, the Universal Camouflage Pattern (UCP) uniform has finally and mercifully been completely phased out of Army service, replaced instead with a uniform in the Operation Camouflage Pattern (OCP). Of note the uniform will still be referred to as the Army Combat Uniform (ACU).
