  • Directed Shot-type countermeasure munitions (like Trophy).
  • Rocket-Towed Barrier countermeasure munitions. The promise of this technology is the ability to defeat simultaneous incoming threats without any potential for local fratricide.

The big radars infront of the turret frontal armour are the first thing to be hit by whatever shoots on the tank. Even the turret rotation among bushes or in any tight environment can damage them because they move at very wide circle. Don't know if it can be solved in a different way with Leo II, but I feel like in a real combat environment they will be damaged or destroyed pretty quickly just like similarly placed IR searchlights usually were.

   Project from late 70s of Soviet MBT (Object 478M) with Shatyor APS.

 Boxes on the side are probably radars (other components were mounted on rear plate of the turret), interceptors are visible in the roof of frontal armor of the turret.

The tank was supposed to use the Shatyor active protection system, which defends the sector of 200 degrees, the number of cluster rounds - 20 pieces, the probability of hitting incoming shells - 0.7-0.8.

   Launchers of interceptors are visible just above smoke grenades mortars:

   Maybe earlier development that led to Arena APS, as they have plenty of similarities.

The sensor is not actually displayed in the article, and its type is not even mentioned, but it's IAI's OTHELLO, an EO sensor that pinpoints hostile fire location (if within LoS).

The 188th armored brigade is already equipped with it.

The hybrid protection module is basically a combination of the ADS active protection system and passive armor. Basically components of the APS are sandwhiched between layers of passive armor, thus allowing to mount the hybrid protection module on common add-on armor interfaces and reducing the impact on internal volume, while the APS remains protected without the need of further armor.

The prototype of the HPM showcased in 2019 consisted out of two high-hardness steel plates, each individually providing protection according STANAG 4569 Level 2. Both plates used in a spaced configuration (with parts of the ADS in-between) supposedly provided protection according to STANAG 4569 Level 5 (at least according to the EDR Magazine) and provided a weight saving of 35% compared to using the ADS and add-on armor independently.

 

Rheinmetall offers the hybrid protection module for all protection levels covered by STANAG 4569 and evben beyond that. Depending on the required level of protection, the armor plates might be instead made of a ceramic laminate or other materials.

   Closer look at Arena-M version, screengrabs from Military Acceptance episode. Note that module have 4 launchers now (8 total if we count on module on other side of the turret), 2 of which are for 2 countermeasures each, and 2 are for single countermeasure munition. Launchers for 2 munitions have them placed at an angle, while it looks for me that single ones are placed vertically/much less angled.

   So 4x2 + 4x1, giving Arena-M 12 countermeasures in total.

   According to Military Acceptance episode, this tests are 2 years old. Presenter was calling this system "Sovershenstvovanie-A" or "Improovment-A", which i suspect is name of R&D, and not system itself.

   Unrelated - Shtora deployed smoke grenades.
