2. Armour-piercing ammunition - Wikipedia

   en.wikipedia.org/wiki/Armour-piercing_ammunition

   Projectiles designed for this purpose have a greatly strengthened body with a specially hardened and shaped nose. One common addition to later projectiles is the use of a softer ring or cap of metal on the nose known as a penetrating cap, or armour-piercing cap. This lowers the initial shock of impact to prevent the rigid projectile from ...

3. Armour-piercing fin-stabilized discarding sabot - Wikipedia

   en.wikipedia.org/wiki/Armour-piercing_fin...

   Modern 120 mm tank gun shells. KE penetrators for modern tanks are commonly 2–3 cm (0.787–1.18 in) in diameter, and can approach 80 cm (31.5 in) long. As more structurally efficient penetrator-sabot designs are developed their length tends to increase, in order to defeat even greater line-of-sight armour depth.

4. Primer (firearms) - Wikipedia

   A "hammer" which also had half-cock (for loading and applying the cap) and full-cock positions replaced the cock. When released by pulling the trigger, the hammer would strike the cap, crushing it against the nipple. The percussion cap was a thin metal cup that contained a small quantity of pressure-sensitive explosive, often mercury fulminate.

5. High-explosive squash head - Wikipedia

   en.wikipedia.org/wiki/High-explosive_squash_head

   This fragmentation by blast wave is known as 'scabbing' or 'spalling', with the fragments termed 'scabs or 'spall'. [4] [2]Depending upon the armour thickness, a heavy piece of target material (4 to 10 kg (8.8 to 22.0 lb) for a 120 mm (4.7 in) round used in Arjun MBT [4]) can separate out from the other end of the target with supersonic velocities.

6. Push feed and controlled feed - Wikipedia

   en.wikipedia.org/wiki/Push_feed_and_controlled_feed

   This means that it is possible to feed a round directly into the chamber, as is possible with push-feed designs. Push feed mechanisms on the other hand have an extractor which is designed to move around the rim of an already chambered round, and the cartridges can therefore either be fed via the magazine or hand fed directly into the chamber ...

7. M-1956 load-carrying equipment - Wikipedia

   en.wikipedia.org/wiki/M-1956_Load-Carrying_Equipment

   The M-1956 LCE continued application of the belt-supported-by-suspenders concept, adopted by the U.S. Army at least as early as the pattern 1903 equipment. [2] The M-1956 "Belt, Individual Equipment" or pistol belt differed little in form and function from the M-1936 pistol belt and would accommodate any of the pouches and equipment that would mount on the M-1936 belt.
