Often the sheer bulk of stores carried by the vehicle provide some protection against small arms. It would be prudent for such vehicles to have some armor in key areas such as the radiator grill, gunshields, windshield, seats and tailgate. Because they operate so deep in enemy territory artillery splinters are not a major concern in special forces operations.
This site offers several interesting systems suitable for use on Deep Reconnaissance vehicles. These include swing arm mounts for MGs, sufficient light armour to break a contact and outward facing rear seats. Vehicle illustrated is a HMMWV with a useful rear cargo area as well as four seats, in contrast to the more common Armament Carrier variant. Many of these features could be applied to other types of Deep Recon vehicle. Probably the most logical choice for a DRV is the ubiquitous Mercedes-Benz Unimog which is used by many armies including those in the Middle East and Africa. Such a vehicle could carry four crew, a motorcycle, armament and a useful quantity of stores. When fitted by a tarpaulin such a vehicle would resemble and unarmed supply vehicle.
RPG and mortar fragments may be a concern in a Counter-insurgency operation such as Iraq at present which is why more conventional light armoured vehicles like the M113 should be used in such situations.
