Abstract: Summary: A limited test program was conducted to compare the performances of the M135 and M211 2-1/2-ton military cargo trucks while operating with and without snap-tracs on a silty, wet soil. The vehicles gave limited performance while operating without the traction device, but greatly improved performance when they were equipped with snap-tracs. It was concluded that the use of snap-tracs did not improve the flotation characteristics of the trucks, but did significantly improve their traction characteristics in an extremely wet, soft, slippery soil. However, it was not possible to determine positively whether the C-shaped members of the snap-tracs "open" and act like grousers under the wheel. Additional tests are recommended to compare the performance of the unmodified snap-tracs with the performance of snap-tracs with the C-shaped member locked in place and with the C-shaped member removed.
