Armored Personnel Carrier. APCs, usually armed with machine guns, generally transport infantry to the battle and then the troops dismount to fight on their own. APCBC
Armor- Piercing, Capped, Ballistic Capped. Armor-piercing projectile that has a piercing cap installed over the projectile's nose to help prevent projectile break-up when encountering face-hardened armor. Since piercing caps were typically blunt, aerodynamic ballistic caps were then installed over the piercing caps. During World War II, the US did not nomenclaturally differentiate between APC and APCBC projectiles; e.g., the 75mm APC projectile M61 had a ballistic cap fitted as well. APDS

Armor-piercing projectile that is smaller than the diameter of the gun's barrel. Sabots (French for "shoe") are placed around the projectile and fill the space between the projectile and barrel walls. Once the projectile clears the gun tube, the sabots fall away. APDS projectiles have a higher muzzle velocity than comparable full-bore projectiles.

Counterintelligence/ Human Intelligence Automated Tool Set. Christie suspension
The suspension designed by J. Walter Christie in the 1920s involved independently springing a vehicle's road wheels on tall vertical helical springs. The wheels were attached to swing arms which then connected to the springs. The springs required a tall double-walled hull, and they were placed in between the two hull layers. Many vehicles with Christie's suspension could drive on or off of their tracks, wheeled motion usually being powered by chains running from the sprockets or final drives. Among vehicles using variants of Christie's suspension were many British World War II-era cruiser tanks, and the Soviet BT series and T-34.

This suspension transmits pressure from the road wheel arm to compress a volume of gas via hydraulic fluid from which the gas is separated by a piston. By pumping or draining fluid into the suspension, the road wheel can also be raised or lowered.
Armor-piercing projectile that has a dense tungsten core surrounded by a lightweight, aerodynamic metal body. The light weight of the projectile imparts a higher muzzle velocity, and this, along with the relatively small diameter of the piercing core, yields greater penetration compared to conventional projectiles, especially at shorter ranges since the lighter HVAP projectile will bleed off speed more quickly than a heavier conventional projectile.

TOW Bushmaster Armored Turret, 2-man. TC
Tank Commander. Torsilastic suspension
This suspension used wheels attached to a suspension arm which was sprung with a rubber spring. Used, for example, on many US LVTs, the rubber springs possessed the obvious advantage of being immune to corrosion, a great benefit on amphibious vehicles.
Torsion bar suspension
This suspension type predominates among modern tracked vehicles. The road wheels are independently sprung, and attached by swing arms to the torsion bars, which are made from specially-treated steel and which run from the road wheel swing arm to an anchor on the other side of the hull. The torsion bars twist in response to wheel movement and provide a large amount of wheel travel. Vehicles with torsion bar suspension usually have their opposite road wheels slightly offset from each other since most torsion bars run the width of the hull.
Torsion tube over bar suspension
A torsion tube operates on the same principle as a torsion bar. When placed over a torsion bar, a torsion tube will twist once the bar has reached its limit and therefore allow more wheel travel than a torsion bar alone.

M4A1(76)W Sherman. Wet ammunition stowage. In tanks with wet ammunition stowage, main gun ammunition was stored in double-walled boxes. In between the walls of the ammunition boxes was a mixture of water, antifreeze, and an anticorrosive agent. When the boxes were penetrated, the water delayed or eliminated the resulting ammunition fire, giving crews valuable time to escape. More importantly, the ammunition was moved from the tanks' sponsons to under the turret, a much safer place for ammunition storage. Walker, Lieutenant General Walton Harris
3 Dec 1889-23 Dec 1950. US 3rd Armored Division and XX Corps commander during World War II, and Eighth Army commander in the Korean War.
