The Offshore Raiding Craft (ORC) is a small, fast boat used by the Royal Marines for troop insertion, and patrols.[2] The ORC is primarily used when undertaking strategic raiding missions, where speed and covertness is desired.[according to whom?] However, it is equally capable when conducting larger scale amphibious operations alongside the larger and more traditional LCACs, LCUs and LCVPs.[according to whom?] [3]

There are two variants of the ORC:[4][5]

  • Mid Console Variant (MCV), a.k.a. the Fire Support Variant
  • Aft Console Variant (ACV), a.k.a. the Troop Carrying Variant

"...a new model of their offshore raiding craft (ORC) - the somewhat uninspiringly-named mid-console variant, but let's call it the gunboat as that sums up its role so much more graphically. The existing ORCs - the troop-carrying variant - are designed with the console (the bit where you drive the thing) at the back of the craft, with seats for up to eight men in front...In these new ORCs, the console sits in the middle, allowing the gunners to be arrayed to cover every angle; this gunboat lives up to that title"

We’ve got the troop carrying variant, which can take six people and deliver them onto a beach, and then we’ve also got the fire support variant and that’s our kind of protection while we’re out on the water."
