  English Acronyms
APFSDS Armor Piercing, Fin Stabilized, Discarding Sabot; a type of anti-tank rounds that defeat an armored target by means of kinetic energy of a subcaliber projectile placed inside of a sheath, or 'sabot', that is discarded in flight. Russian APFSDS rounds have a designation 3BM[number].
APS Active Protection System; a system that automatically intercepts threats that attack the protected object in the immediate vicinity of the object. Essentially the APS is a super-close-in system of "anti-missile defense" that creates an "active" zone of protection at a safe distance around the objects. (See Arena APS)
ATGM Anti-Tank Guided Missile
EFC Effective Full Charge; the measure of gun barrel life, or conversely the amount of erosion exerted on a barrel by a round of a particular type. Generally HEF or HEAT rounds have EFC of 1, while APFSDS rounds have EFC rating that can reach 5.
EOCMDAS Electro-Optical Counter-Measures Defensive Aids Suite; a system that interferes with the operation of guided munitions and FCS, degrading their effectiveness. (See Shtora EOCMDAS)
ERA Explosive Reactive Armor; an applique armor that consists of a HE layer between two metal slabs. When a HEAT round strikes a ERA package, HE layer detonates inducing a spin of metal slabs which causes HEAT jet to collapse or lose penetrating power. Modern Russian ERA is also effective against APFSDS rounds. (See On ERA, Kontakt-5 ERA)
FCS Fire Control System; a complex of targeting, rangefinding, fire solution computation, and sensor equipment that enhances the fire accuracy, especially at long ranges.
HE High Explosive
HEAT High Explosive Anti-Tank; a type of anti-tank rounds that defeat an armored target by means of a hyper-velocity jet that is formed when a charge consisting of a concave metal hemisphere or cone (known as a liner) backed by a high explosive detonates. Russian tank HEAT projectiles have a designation 3BK[number].
HEF High Explosive Fragmentation; a type of rounds that contains a HE charge together with preformed hitting elements or a controlled fragmentation layer, increasing its anti-personel effectiveness. Russian tank-carried HEF projectiles have a designation 3OF[number].
MBT Main Battle Tank.
NBC Nuclear, Biological, Chemical; the use of these types of weapons on a battlefield, or tanks equipment designed to protect the crew from the effects of these weapons.
RHA Rolled Homogeneous Armor; a process of armor manufacturing that ensures its uniformity and enhances resistance to penetration. Often used in the same sense as RHAe.
RHAe Rolled Homogeneous Armor Equivalent; an equivalent RHA thickness of a given armor package against a given type of threats in terms of penetration resistance. Modern armor packages may be several times more efficient against certain threats than RHA of the same thickness.

(I have received a version that this, historically, stands for Broneboinyi Moschnyi (Armor-Piercing Increased Power). Might be... The quest continues)
