Background

M1a2tusk



The mid 21st century saw significant changes in material and computer technologies with nothing more significant than the creation of new ultra-light/ultra-dense materials, by the German corporation Triax, which contributed to both areas of development. As such nations the world over almost immediately began applying these technologies to not just every day life but their militaries as well since most if not all militaries of the world had seen many years of stagnation with the global peace that had grown.

The United States was no exception having survived decades of political strife and recovery. One of the first items the US military upgraded with new armour plating using this material was of course the M1 Abrams, which had not seen any major upgrades in over 20 years, since the wide spread deployment of the M1A3 model. This was due to the fact manufacturing capabilities were not quite up to snuff in order to maximize the potential of the new super hard/tough materials. Dubbed the A4 model it featured some other useful upgrades as well such as solid oxide fuel cell technology and a number upgraded upgraded sensory packages. It's speed and range were both increased along with the added protection of the new armour. It's one drawback was it was not a completely new material constructed vehicle so it did not provide the same kind of protection of the later A5 model, that was concurrently on the drawing board awaiting manufacturing to catch up to the modern materials, would. The A4 served well, however, as the testbed until the A5 was fully deployed in the early 2060s at which point a large number were sold off to allied poorer nations, where they held their own until the introduction of power armour and smaller robot combat vehicles of equal or even greater capability.

All other attacks (1d4x10+1/41 to 4d4x100+199/1799 damage in a single attack/blast) must successfully strike the unit and equal/exceed the Armour Level to do damage.

Bonuses and penalties

Use vehicle combat training


Systems of Note

Solid Oxide - Gives the unit an operational time frame of 4 weeks of constant use. Up to a year with non war time usage.

Radar - Range of 12km. Able to track up to 15 targets, display 10 targets and lock onto 4 targets at once.

Air Defense Radar - Range of 58km. Able to track up to 45 targets, display 30 targets and lock onto 8 targets at once.

Radar Warning Receiver - Warns of potential Radar Lock. Range - equal to Radar or Air Defense Radar respectively.

Targeting Computer - +3 to strike with all on board weapon systems. Range is equal to the radar systems.

Combat Computer - Calculates, stores and transmits data onto a HUD (heads up display) of the pilot's (or other crew members) helmet. Typically tied into the units targeting computer. Hold hundreds of entries about various enemies. Range is equal to the radar systems.

LIDAR/LADAR - This system uses lasers to detect and image items as small as 10cm at 3.2km, as small as 150cm out to 8km and as small as 500cm out to 16km. This system also assists the other sensors in detected and identification. This is not typically a passive system and but be directed at specific targets.

FLIR - Advanced forward looking infra-red system for night operations. Range - 15km

Motion detector/Collision Warning System - Range 75m

Standard instrumentation - Speedometer, altimeter, distance traveled, inertial mapping system (zeroed on your deployment location/home base), power system temperature, ammunition counters, damage assessment indicators.

Radio Communications - long-range direction communication systems out to a range of 750 1280km that can be boosted if proper signal towers or relay systems are in place. Also a directional short-range radio with a range of 80km. Both radios have full encryption capabilities.

Satellite Uplink capability - This allows the craft to communicate over vast distances by connecting to and communicating through the various satellites in orbit.

Complete Environmental Pilot and Crew Compartment - A completely computer controlled life support system that includes: internal cooling and temperature control, air purification and circulation systems (gas filtration, humidifier/dehumidifier) that engages when needed and can recirculate breathable air for up to 36 hours if necessary, computer controlled independent oxygen supply and purge system that has up to 12 hours of breathable air that automatically engages in low oxygen or contaminated air environments, insulated high temperature resistant shielding for up to 300 degrees centigrade (normal fires do no damage though nuclear, plasma, and magical fires do full damage), radiation shielded up to 200 rads, and polarized and light sensitive/adjusting tinted viewport.

External Direct Line Communications - Essentially a hardline "phone", mounted externally on the tank, allows those outside the tank to communicate with the crew inside the tank without need of wireless comms, in order to avoid possible jamming or other interruptions of information sharing.
