The M1 abrams is growing a tusk(tank urban survival kit). The Tank
Urban Survival Kit, or TUSK, is a series of improvements to the M1
Abrams intended to improve fighting ability in urban environments.
Historically, urban and other close battlefields have been the
worst place for tanks to fighta tank's front armor is much
stronger than that on the sides, top, or rear, and in an urban
environment, attacks can come from any direction, and attackers can
get close enough to reliably hit weak points in the tank's armor,
or get sufficient elevation to hit the top armor square on.
Armor upgrades include reactive armor on the sides of the tank and
slat armor (similar to that on the Stryker) on the rear to protect
against rocket-propelled grenades and other shaped charge
warheads.
A gun shield and a thermal sight system are added to the loader's
top-mounted M240B 7.62 mm machine gun, and a Kongsberg Gruppen
Remote Weapon Turret carrying a .50 machine gun is in place of the
tank commander's original .50 machine gun. An exterior telephone
allows supporting infantry to communicate with the tank
commander.
The TUSK system is a field-installable kit that allows tanks to be
upgraded without needing to be recalled to a maintenance
depot.
While the reactive armor may not be needed in most situations in
maneuver warfare, items like the rear slat armor, loader's gun
shield, infantry phone, and Kongsberg Remote Weapons Station for
the .50 machine gun will be added to the entire M1A2 fleet over
time.
In addition to this, a Transparent Armor Gun Shield may also be
implemented.
