It is called the Ripsaw, a developmental unmanned light tank built by the Howe brothers in 2000 as a small family project. It is able to accelerate to 60 mph (100 km/h) in about 4 seconds. The vehicle caught the interest of the U.S Army in 2001 during a Dallas vehicle show. The Ripsaw can be built for about $200,000 - $250,000.
The “Sham II” is the latest armoured tank built by the Syrian rebels in their fight against the brutal regime of President Bashar al-Assad. It took a month to design and assemble the machine, which has five cameras and a 7.62mm machine gun attached to its frame. The machine gun is controlled by control stick from a Sony PS3 games console from inside and although the 2.5 cm thick metal walls cannot withstand a grenade or tank fire, they can reportedly resist up to 23 mm cannon fire. The tank cost approximately $10 000 to build.
