Overview:
The M1A3 Abrams II is the newest Main Battle Tank (MBT) in Fells Point. Developed from the M1A2 Abrams SEP, the M1A3 combines next generation technology and weapons systems with the old.

One of the many upgrades from the M1A2 Abrams SEP is the addition of an Active Protection System that utilizes both the Iron Fist system developed by Israel Military Industries, and the regionally developed Cavalier Weapon System. Also in use by the M1A3 is a chaff/smoke grenades launches as well as the ability to produce a smoke screen by using it's 1,650 horsepower turbine engine.

The Iron Fist APS combines both soft and hard kill capabilities into one, using a jamming system to defeat guided missiles, as well as having the ability to launch an explosive charge to deflect munitions such as unguided rockets and even kinetic penetrators. Several modifications have been made to the system, which includes increasing the number of projectiles per tube to two by using a method similar to Metal Storm, and the expansion of it's soft countermeasures to include a wider variety of missiles. In use with the Remote Weapon turret, the Jennings & Rall Cavalier Weapon System, which uses the Vulcan cannon to destroy missiles via hard kill.

The Abrams II employs Dorchester Level III armor, a upgraded version of what is known as Chobham armor, with reactive-armor tiles on the exterior of the tank to increase protection. Slat armor has been added to the rear of the tank to detonate ordnance before striking the vulnerable powerplant to decrease the amount of damage dealt to the tank. The M1A3 also sports full Nuclear, Biological, and Chemical protection which allows the Abrams II to operate in environments that have suffered the detonation of a weapon of mass destruction or that has been contaminated in some way.

A L55 Rheinmetall 120 millimeter smoothbore gun makes up the main armament of the M1A3 Abrams II, replacing the L44 version found on the lesser A2 variant. In addition to the main cannon of the Abrams II, a .50 caliber coaxial gun, further complemented by a pintle-mounted M240 machine gun. Two missile launchers are in place on either side of the M1A3's turret, and under a normal combat load will hold four BGM-70 TOW missiles in one launcher, where the other will carry four Starstreak High Velocity Missiles to give the tank both anti-vehicle and anti-air capabilities.

A new assortment of 'Smart' munitions have been created for use with the M1A3, these rounds make use of stabilizing fins similar to what can be found on the XM982 Excalibur 155mm artillery shell. Using millimeter wave RADAR, the Abrams II can guide shells on target or act as an artillery piece by using a GPS guidance system. Also included in the A3 upgrade of the Abrams, an EMP Generator similar to the T-90's EMT-71 system used to destroy magnetic mines affords the Abrams II the ability to render mines inert, and can be used to destroy electronic equipment used by enemy militaries. The view ports on the Abrams II are now complemented by digital cameras which allow the crew a 360 degree view of the battlefield in Infrared, Optical, and Night Vision modes.

The Intervehicle Information System (IVIS) is also integrated into the Abrams II, which significantly increases the combat effectiveness of M1A3 units as IVIS allows vehicle crews to connect to a tactical map able to be updated with positions of various combat obstacles and enemies, and even friendless nearly nullifying the "Fog of War". An overhauled communications suite gives tankers the ability to access satellite networks as well as numerous secure radio channels; also added are new datalinks which can transfer and deliver information on par with wired data networks used by the military.

Units are now available for sale on the international market to stable, established nations pending approval from Jennings & Rall. An upgrade package is offered for existing M1A2 SEP tanks, however does not include installation and the costs for stripping older systems out of M1A2 Abrams.

Communication with satellites and what not was achieved in the SEP, with the battle management system. It organizes battlefield data into one program, which allows the tank commander to know the situation around him. Inter-tank communicated is carried out through text messaging, actually.

There is actually a newer gun currently undergoing testing; that's the XM36, which was originally supposed to be mounted on the MCS. It's based on the XM291, which was a lightweight, high-powered, dual-caliber gun designed in the early 1990s for the M1, in a supposed M1A3 upgrade (Block III, at least). It is electrochemical-thermal (the XM291 was not originally ETC, but was made ETC and was mounted on the Thunderbolt II testing vehicle, based on a M8 chassis and turret and tested in 2004 by BAE Systems). This gun would be more powerful than the Rheinmetall 120mm L/55 tank-gun.

I don't see a reason to mount missile launchers on a tank turret. These will add weight for little added combat value. They are considered valuable on ICV turrets because the turret has no anti-armor capability, otherwise. There are gun-launched missiles which exist, and I would suggest instead. They do not have the disadvantages of externally mounted missile launchers, and can be used both against air and ground targets (i.e. Israeli LAHAT).

I suggest placing metal slats all around the tank, rather than in a single spot. Of course, this would heavily limit the effects of any reactive armor. The reactive armor is actually a comepletely seperate component, seeing as the boxes have to be replaced every time they are activated. Everything else has been previously said.

There is the issue of the "vulcan" gun apparently mounted as soem sort of additional APS.

I hate to say it but this:

Is what a Vulcan set up to hit small targets looks like on land. of coruse you might not be using the 20mm M61 Vulcan but it is a bit silly to use it's name if you aren't. You might be able to get away with a 5.56 or 7.62mm gatling gun but really a good APS like Iron fist is much much better. Adding extra stuff just adds complications and makes thigns a lot more difficult.
