Polaris Defense has begun deliveries of off-road vehicles to the U.S. Special Operations Command under a contract signed last month.

The vehicles are MRZR 2 and MRZR 4 ultralight platforms, which feature a standard winch, electronic power steering, aircraft tie-downs, fold-down rollover protective structures, large cargo boxes, IR light capability and blackout modes.

The contact received by the Minnesota company is a five-year indefinite-delivery/indefinite-quantity award worth $83 million. It includes contractor logistics support.

Polaris has been supplying the vehicles to USSOCOM since 2013.

"We've been providing the MRZR for three years to USSOCOM and this contract reiterates that ultralight mobility is still a critical component of Special Operations Forces missions," said Polaris Defence Generl Manager Rich Haddad. "These are extremely configurable platforms, providing operators the ability to quickly prepare for missions even in the most extreme terrain.

"MRZRs provide extreme mobility SOF can count on, that deploys in tactical air, providing maximum flexibility."
