Navy SEALs with SEAL Team 17 drive a Ground Mobility Vehicle (GMV) through a simulated city during mobility training.
The SEAL variant of the GMV is the GMV-N.
These vehicles can be fitted with armor kits, as shown here to make them suitable for working in urban environments.
Note the shielded turret atop the GMV-N which protects the vehicle's main gunner who may operate a M2 heavy machine gun or 40mm grenade launcher.
