June 2, 2004: The U.S. Army, while eager to design and build its new, twenty ton, FCS (Future Combat System) tank, it was reminded in Iraq that the current 65 ton M-1 tank still rules the battlefield. As a result, the current plan is now to keep the M-1 in service until at least 2030. This means that there will be more upgrades for the M-1, including anti-missile systems (using electronic signals, lasers, smoke and whatever works) and battlefield Internet capability. The FSC is seen as too ambitious, depending on too many technologies that are still in the lab, and may never make it to the battlefield, or at least not in the next decade or so.
I think Electronic warfare parameters are the key..and one should consider that Pandoras box will indeed open..and we will see EMP and modulating EMP weapons used to defeat interlocking com grids.
Other electronic warfare goodies..designed to backdoor into computers and rewrite the hardware..or tie it up in a loop..which cannot be undone by rebooting.
searing a computer via its attenna and reciever systems.
Mines with kinnetic energy driven spikes...motion sensor, pop up and split a tanks engine block in seconds.
