The new Israeli tank Merkava Mk4 Barak entered service with the troops. The Israeli Ministry of Defense has officially announced the entry into service of a new modification of the Merkava Mk 4 Barak tank. The first tanks were received by the 52nd tank battalion of the 401st armored brigade of the Israeli army. The tank was announced before the situation in Israel worsened. The development of the tank began in 2015, the main innovations affected electronics. In the Merkava Barak tank, a new fire control system was introduced with the Makhshev Mesima task computer, which uses elements of “artificial intelligence”. The computer automatically identifies targets and distributes priority for their destruction, displaying an enlarged image of the target on the commander’s display. At the same time, “Makhshev Mesima” independently determines the type of projectile suitable for hitting the enemy, measures the range to the target, makes corrections for firing and aims the gun. The tank was also connected to the TORCH-X automated combat unit control system as part of the concept of network-centric warfare. The tank now has an Iron Vision system, which allows the crew to see everything that is happening around the tank at 360 degrees, day, night, in rain and fog. 46 computers and dozens of cameras record movement, identify dangers and transmit data. The information enters an electronics unit mounted on the commander’s helmet, and after processing in the form of a projected image, it is displayed on a small screen in front of the tankman’s eyes, as if wearing augmented reality glasses.
