for those who do not know what active protection systems are read:
An active protection system, or APS, protects a tank or other armoured fighting vehicle from incoming fire before it hits the vehicle's armour. There
are two general categories: soft kill systems, which use jamming to confuse a missile's guidance system, and hard kill systems, which attempt to
detect and destroy incoming projectiles.
soft kill systems :
shtora jammers (made in russia)
Shtora is a Russian electro-optical countermeasures suite for tanks, designed to disrupt the laser target designation and rangefinders of incoming
anti-tank guided missiles (ATGMs).
The system is mounted on the Russian T-80 and T-90 series tanks, the Ukrainian T-84, and the Serbian M-84AB1.
Shtora-1 is an electro-optical jammer that jams the enemy's semiautomatic command to line of sight (SACLOS) antitank guided missiles, laser
rangefinders and target designators. Shtora-1 is actually a soft-kill, or passive-countermeasure system. It is most effective when used together with
a hard-kill system such as the Arena active countermeasures system. The system was shown fitted to a Russian main battle tank during the International
Defense Exposition, held in Abu Dhabi in 1995. The first known application of the system is the Russian T-90 main battle tank, which entered service
in the Russian Army in 1993.

hard kill systems :
Drozd (made in russia)
ARENA (made in russia)
TROPHY(made in israel)
Iron Fist (made in israel)
out of these , Iron Fist is the only that is capable of intercepting kinetic penetrators
drozd was the active protection system developed read:
The 1030M Drozd APS uses small rockets placed in fixed silos to both sides of the turret to defeat incoming ATGMs. The millimeter radar on the
rear of a turret tracks the missile and fires the rocket from a silo that points in that direction. The rocket detonates, producing the stream of
fragments that destroys the incoming projectile.
The system was installed on marine units' T-55 tanks (designated T-55AD, D signifying Drozd) in 1983.
This system had substantially less capability than the Arena APS in range of protected angles, number of incoming projectiles, and reliability of
interception.
The Drozd-2 system that is being marketed today as an upgrade option for T-80U MBT offers several significant improvements over the original version,
the most important being the drastically increased range of protected angles, as well as decreased projectile size and increased number of
projectiles. This new system may be not inferior to Arena APS

ARENA (made in russia)
The Arena tank active protection system belongs to the latest generation of Russian APS, together with Drozd-2 APS.
Arena is intended to protect tanks from antitank grenades and ATGMs, including some variants of top-attack ATGMs.
The system incorporates the following engineering solutions:
use of a multi-functional millimetre radar with "instant" scanning of all protected sector to detect and track antitank targets;
use of focused instant-effect protective ammunition for aimed destruction of incoming targets;
control equipment, represented by a specialized computer that provides automatic control over radar operation and system as a whole, as well as device
for serviceability control of the system and its integrated parts and units.
Protective ammunition is housed in silo sections arranged around the turret. The rack-mounted radar is fixed on the turret roof. All other equipment
is housed inside the turret. Connecting cables from the turret run inside the radar rack without affecting the sealing of the fighting compartment.

Arena on a battlefield
In combat mode, the radar continuously searches for incoming projectiles. Once the threat is detected the radar switches to the target tracking mode,
in which the data on the moving target is obtained and entered into the computer, which uses it to select the most appropriate silo and determine the
time for its activation. At the determined moment, the computer generates command signals to the selected protective ammunition. The later is launched
upwards and detonates, creating a directed stream of destructive elements which destroys any target within this field, eliminating the shaped-charge
effect of the threat or reducing it to levels that are not dangerous to the tank.
In emergency the commander (operator) can manually operate and detonate protective ammunition from the control panel.
The number of unused protective ammunition is displayed on the control panel screen.
Each protective ammunition protects a certain azimuth sector, with destruction zones of adjacent ammunitions overlapping each other, thereby
intercepting the targets repeatedly approaching the tank from the same direction. The number of mounted protective ammunition is expected to be
usually sufficient to defeat all the threats to the tank during a single combat mission without replenishing the protective ammunition.
The system operates in any weather, round the clock, detects and engages targets under all conditions of tank combat employment, including while on
the move with a turned turret.
