When opening the game today I came across new ammunition for the American 120mm cannons. The M908, in the game referred to as the M908 HEAT-MP.
However, a quick search, and you discover that the M908 is actually an HE. M908HE-OR-T is its real name. In turn, it is a high explosive, obstacle reduction, tactical service round with tracer.
But in the game it came as a HEAT Multipurpose, basically being a past copy of the M830A1 and even being made worse, penetrating less. If they want to put an HE for American tanks, let it actually be an HE, not this kind of HEAT
This cartridge is a high explosive, obstacle reduction, tactical service round with tracer. The M908 is used in the 120mm, smooth bore M256 cannon.

The Cartridge; 120mm, HE-OR-T, M908 is a high explosive, obstacle reduction, tactical service round with tracer. The M908 is used in the 120mm, M256 smooth bore tank and is a fin stabilized round with a discarding sabot. The baseline design contains a propulsion system consisting of a combustible cartridge case, case adaptor, nineteen-perforated hexagonal JA-2 propellant, a propellant containment device (cloth bag), and an M129 primer assembled to a metal case base and seal assembly (all are currently used on the M829A1). The projectile consists of a subcaliber projectile and three piece aluminum sabot. The subcaliber projectile combines a fuzing system and a chemical energy warhead (Composition A3 Type II). The three segment sabot is secured to the warhead body by a nylon obturator and a steel retaining ring. The fuzing system includes: M774 base element, flexible communication circuit, and frontal impact switch assembly (FISA). The conical nose of the projectile consists of the FISA coupled to the warhead body and a steel nose coupled to the FISA, which closes upon impact with a ground target. A flexible electrical cable carries the signal of FISA closure to the M774 base element. An inertial switch in the M774 base element act as a backup to the FISA. Either switch will delay the function of the warhead beyond the point of impact with the target. This delayed functioning is ideal for the reduction of concrete ground targets.
The M774 base element is a dual environment safe and arm (S&A) device. The M774 receives an electric firing pulse from the FISA which then triggers the base element electronics to fire the M69 electric detonator. The M69 detonator is contained in the rotor which provides a physical separation of the M69 detonator from the fuze electronics until the subprojectile has traveled a safe distance downrange. The first safety feature of the mechanical S&A lock consists of three leafs and a spring, originated so as to release the rotor upon forward acceleration. The second safety feature is a drag weight which senses the decelerating force/drag of the projectile as it leaves the muzzle. As the drag weight senses drag, it moves out of the way of the rotor allowing the rotor to rotate to the armed position as designed.
Once the M774 base element is armed and receives an electrical firing pulse to trigger the detonator, the detonator, lead, booster, and warhead explosives initiate in sequence destroying the target. The explosive train located in front of the base element consists of the lead cup, booster, and Comp A3 explosive. The warhead explosive is contained in the body with a shaped copper liner, in front of the booster. The liner provides the penetration capability for the system.
An aluminum fin assembly with tracer is attached to the aft end of the subprojectile by way of an aluminum fin adaptor. The fin has beveled leading edges and T-tabs on the outside diameter to increase the effective fin area. Spin, which is inducted by a twist in the fin blade, provides the subcaliber projectile with greater in-flight stability and accuracy.
