Power distribution throughout the tank has been improved, relying on multiple bus paths so that in the event one conduit is damaged, power may still be delivered to a component via an alternate path. In addition to IVIS and the CITV, the M1A2 incorporates a number of additional electronic upgrades. This CITV sight allows the commander to independently scan for targets in all weather conditions and through battlefield obscurants. Improving on the "hunter-killer" tank commander-gunner target hand off method pioneered on the German Leopard II, the M1A2 takes this a step further by providing the Tank Commander with an independent thermal sight. To ensure information security, all IVIS data transmissions are routed through the M1A2's SINCGARS radio system. M1A2 Abrams tanks from the 1st Cavalry Division participate in a live fire training exercise. Lastly, map graphic control measures and operational orders can be rapidly distributed via the IVIS system. In addition enemy positions can be identified, plotted and disseminated, while reports and artillery requests can be automatically formatted, transmitted, and processed. By incorporating information provided by an on board Position/Navigation (POSNAV) system, unit commander's can track the location and progress of subordinate elements automatically, without tasking vehicle crews. Most notable of these improvements is the addition of the Inter-Vehicle Information System (IVIS.) The IVIS system allows for the automatic and continual exchange of information between vehicles. Internally, however, the M1A2 has been radically redesigned to take advantage of newer technology. Outwardly similar in appearance to the M1A1, the most notable exterior changes on the M1A2 are the redesigned Commander's Weapon Station (CWS) and the addition of a Commander's Independent Thermal Viewer) on the left side of the turret forward of the loader's hatch.
