Summary
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]

Commando Raiding Craft edit
In 2023, 23 of the original 35 ORC were reportedly donated to Ukraine. They were replaced in U.K. service by the upgraded Commando Raiding Craft (CRC). The CRC is fitted with three general purpose machine guns or .50 heavy machine gun mounts, as well as protection against enemy fire for the troops inside. The CRC has a speed of up to 40 knots, a range of 200 nautical miles and can be underslung from a helicopter or deployed from ships of various sizes. They incorporate a new configuration with driving position moved from the back to front for better manoeuvrability and employ a more sophisticated electronic suite for communications and navigation.[6]

...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

So the ORC is our jet boat and we've got two variants. 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.
