M-125 Dornan IFV
The M-125 IFV serves primarily as a successor to the M-124 MacArthur IFV, which saw many long years of service during World War Three and the early years of the current US Federal government campaign to restore lawful and legitimate government to United States territory. The M-124, while serviceable, had many design flaws - for instance, PA soldiers had to stand and could only be held six in a vehicle, the driver-controlled 76mm guns were more a distraction for him than anything useful, it had a number of shot traps at the front, and it was too tall for its length causing it to tip over when rounding corners, a consistent flaw.
So, in the last years of President Fairfax's administration a program was set in place to design a new IFV, with the Hermes Automobile Corporation winning the prize. The result was not an all-new design, but a refining of the principles used by the MacArthur. The name was decided in the early Kirkpatrick administration, shortly after the last Navarro veteran known to have made it to Federally-governed territory passed, after Sergeant Arch Dornan, a notable combat instructor, who is reputed by both US military survivors and NCR accounts to have been slain leading the last charge of US forces against NCR troops that had breached the base's perimeter.
The M-125 has a notably different design shape than the M-124, no longer overly tall in comparison to its length. It retains a gun at top, but this is now an MV-320 30mm rail-autocannon, capable of firing solid, canister, high-ex, incendiary, plasma and chemical rounds as tactical circumstances and mission profile dictates, with a co-axial heavy gatling laser - the main gun uses an autoloader and is controlled remotely by a gunner who sits next to the driver in the vehicle's armoured control cabin.
Additional features include smoke grenade launchers which also serve to scramble the vehicle's IR signature, and electro-reactive armour tiles. The M-125 can carry 13 power-armoured soldiers, or 18 non-armoured soldiers, sitting in its rear compartment - they deploy via a ramp which goes down from the back.
The IFV also has several variants which forego its transport capacity to be of more direct effectiveness on the battlefield:
M480 "Electric Edith"
A self-propelled artillery piece, the M480 replaces the 30mm rail-autocannon and all troop transport capacity with a 155mm rail-howitzer capable of a maximum effective range of 25 miles. It fires all rounds fired by the M-360 towed howitzer, which is still in service.
M180 "Grid Square Removal System"
Also nicknamed the "Rockin' Rhonda", the M180 is a self-propelled rocket artillery piece intended for saturation bombardment of enemy positions, which also has no troop transport capability.
M90 "Lazy Lindy" Laser Air Defence Vehicle
The M90 Laser Air Defence Vehicle replaces its troop transport capacity and the 30mm rail-autocannon with turreted mounting and additional power generation for a twin-linked laser-autocannon capable of hitting and taking down any enemy aircraft within 20,000 feet.
