CLR is unique in that it is able to provide essential supplies for front-line Commando units for the initial 30 days of any operation by the transfer of stores from ship to shore – making it totally self-sufficient.

Based at RM Chivenor in North Devon, the Commando Logistic Regiment role is to ensure the re-supply of ammunition, water, fuel and food, known as "combat supplies" to the ground forces, and provide specialist services to sustain the brigade's operations.

Its primary role is to co-ordinate the command and control function of logistic distribution, relaying stores information by computer from ship to shore and collating field requirements from forward units and assessing their priority of order for delivery or recovery.

The squadron's role is to provide UK Commando Force with 2nd line logistic support that includes transport, stores and bulk fuel.

[6] VIKING Squadron (VS) is a dedicated Royal Marine sub-unit of the Commando Logistic Regiment (CLR) based in Chivenor, N Devon.

The specialisation is formed into a Squadron of four independent VIKING Troops to support fast moving, lightly armoured expeditionary warfare for the Lead Commando Group.

The LTG will provide immediate sustainment to the Battlegroup wherever they are deployed; enabling equipment repair and recovery, logistic supply and distribution and above all, medical support.

Designed carefully to complement the Battlegroup’s organic logistic capabilities, the LTG will enable extra reach and endurance demanded by global operations.

[9] 383 Commando Petroleum Troop of the Royal Logistic Corps is responsible for the handling, supply and storage of bulk fuels from ship to shore and under front line combat conditions.
