The MIL-STD-1168 is a set of standard codes used to identify munitions (ammunition, explosives and propellants). It was designed to replace the previous confusing Ammunition Identification Code (AIC) system used by the United States Army Ordnance Department.
The M1 ammo crate held a total of 1,000 belted or linked rounds packed in 4 M1 ammo boxes and the later M1A1 ammo crate held a total of 1,000 belted or 1,100 linked rounds packed in M1A1 ammo boxes. There were two .50 M2 ammo boxes to a crate (for a total of 220 belted or 210 linked rounds) with a volume of 0.93 cubic feet.
Early ammunition had a 4-digit year with the first 2 digits (thousands and hundreds) at 9 o'clock and the second 2 digits (tens and ones) at 3 o'clock. Ammunition with an E at the 12 o'clock position (which stands for Ersättning, or "Substitute") have a bimetallic cartridge-case (brass-clad steel) due to wartime economy measures during World ...

Armour-piercing ammunition (AP) is a type of projectile designed to penetrate armour protection, most often including naval armour, body armour, and vehicle armour. [1]The first, major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly armoured interiors.
Britain also deployed Palliser shells in the 1870s–1880s. In the shell, the cavity was slightly larger than in the shot and was filled with 1.5% gunpowder instead of being empty, to provide a small explosive effect after penetrating armour plating. The shell was correspondingly slightly longer than the shot to compensate for the lighter cavity.
120×570mm NATO tank ammunition (4.7 inch), also known as 120×570mmR, is a common, NATO-standard (STANAG 4385), tank gun semi-combustible cartridge used by 120mm smoothbore guns, superseding the earlier 105×617mmR cartridge used in NATO-standard rifled tank guns.
For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the concise form is [Ne] 3s 2 3p 3.
