M1A2 SEP V2 TUSK II

The M1A2 SEP v2 (version 2) of the M1A2 Abrams was developed in the mid-to-late 2000s. This upgrade was primarily geared towards the urban combat the Abrams was facing at the time in Iraq.
The SEPv2 added the Common Remotely Operated Weapons Station (CROWS or CROWS II) to the Abrams to allow the commander to shoot at targets from the safety of inside the tank, and improved the side and front armor of the tank with standard mounts for the Tank Urban Survival Kit set of add-on armor. It also added a tank-to-infantry phone for better coordination with a tank’s infantry screen, color displays, better interfaces, a new operating system, and an upgraded transmission for better durability.
The TUSK program was initiated in 2004 to protect the M1 Abrams crews from the threats of an urban warfare environment. There are two TUSK variants, the TUSK I including ARAT I reactive armor, belly armor, CS/AAM, LAGS, LWTS, etc. The TUSK II includes equipment from TUSK I plus ARAT II reactive armor tiles plus a 360°shield for the TCWS and a rear camera.
