A Sherman tank fitted with a T1E3 mine exploder.
These rollers were developed from a series of similar types, that used the weight of heavy metal discs to detonate mines. The T1E3 consisted of 10 steel rollers, each weighing 2100 kg (4600 lbs), that were driven by the tank's sprockets via chains.
Each side could articulate to follow the contours of the ground. In total, the system weighed more than 22,200 kgs (59,000 lbs). A few hundred were built, and the type was used successfully in the latter portions of the Second World War. However their enormous size and weight limited their practicality, and severely reduced the Sherman's mobility.
Photographer CJ Kale waited over 5 years for the conditions to do this shot after 3 days in the 110 degree water swimming with lava bombs and volcanic glass covered on the beach in Hawaii."
