Description

The combat operations of the early 2000s with Operation Iraqi Freedom showcased that the M1A2 System Enhancement Package (SEP) still had rooms for improvements. Combat-oriented upgrades such as the Tank Urban Survival Kit (TUSK) I and II were first fitting to the M1A2 SEP. However, following the cancellation for the US Army Future Combat System program, it becomes clear the M1A2 Abrams will remain the workhorse of the US Army for the foreseeable future, and work began on the next upgrade for the M1A2 Abrams with SEP V2. SEP V2 incorporated many internal changes to the sights, computers and electronics, as well as a new auxillary power unit. The most notable exterior change was the addition of a CROWS (Common Remotely Operated Weapon Station) to allow the commander to remotely operate the heavy machine gun atop the tank. The M1A2 SEP V2 was accepted into service for the US Army in 2008, equipping all Armor Brigade Combat Teams by 2013.

The Tank, Combat, Full Tracked, 120-mm Gun M1A2 SEP V2 was introduced in Update "Air Superiority". The primary differences on the M1A2 SEP V2 compared to the preceding M1A2 SEP is the elevated CROWS for the M2 Browning machine gun and the ARAT II explosive reactive armour that can be attached. The extra weight from these non-removable additions put the M1A2 SEP V2 at around 66 tons, reducing the tank’s overall mobility compared to M1A2 SEP. The only characteristic that went unchanged is the firepower, firing the same shells through the same M256 cannon. The biggest plus of the M1A2 SEP V2 is that player has the opportunity of being able to bring two M1A2 SEP into battle without having to use a backup, which can be an advantage for team composition in its own way.

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.
