Well well the Americans are looking at a wankel in the Abrahams then.
Only as an auxiliary power source though, still it is a start. Eventualy they might even wake up completely and realise the cold war is over and all the mega expensive bits of military macho are completely obsolete.
Light inexpensive and covert suitable equipment is what they need against the AK47 and RPG armed terrorists in millions of square miles of nothing.
Battle tanks are a useless idea.
Even their combat aircraft are pointless. The Taliban can hear them coming 30 miles away. Of course the Americans have the preditor and other drones to kill wedding parties and other miss designated targets with, flown by remote control from thousands of miles away. Another daft idea.
I suppose it beats arcade games but not by much.
There is an answer that is cost effective and fully proven in all the roles needed including dealing with unexploded roadside bombs. Trouble is vested interest prevents the huge change of tactical and strategic thinking needed to start winning out there instead of continualy loosing.
