Mark VII Battle Armour
From Tardis Wiki, the free Doctor Who reference
The newly cloned Sontaran Strax was provided with Mark VII Battle Armour, complete with a Mark VII Tactical Helmet.
According to the Sontaran Subliminal Education Matrix, this version of Sontaran space armour was sturdy, form-fitted and proof against all but the most determined blade or bolt. The armour offered extra protection for the probic vent and could be modified for the inclusion of a perception-camouflage matrix and other advanced technologies. (PROSE: A Soldier's Education)
