[This article describes how they move nuclear material in the UK](https://en.m.wikipedia.org/wiki/Defence_Nuclear_Material_Transport_Operations). Its pretty extensive and no way OP saw this convoy.

For example:


Three organisations are involved in the convoy, namely Fleet Protection Group Royal Marines, AWE civilian personnel and the Special Escort Group.[3]

Convoy vehicles include:-

The Stand Off Escort – Royal Marines provide armed military personnel to counter any potential threat and the SEG’s role is the close escort (security) and traffic management throughout any convoy move.

The Escort Commander's vehicle leads the convoy, navigating the routes and managing the timings by constantly being kept informed of traffic situations up ahead.

The TCHDs, or Truck Cargo Heavy Duty vehicles which carry the nuclear weapons. There are up to five in a convoy. Each AWE driver is accompanied by an armed SEG officer as close escort.

Fire Tender, with staff employed by AWE – the Convoy Safety Officer & Fire Crew

Convoy Commander’s Vehicle, manned by MDP Chief Inspector and his team.

The Traffic Car with two SEG police officers keep traffic behind by putting on a 'rolling block' whenever there is a traffic build up ahead or the convoy approaches hazards such as roundabouts or junctions.

Two miles behind the main part of the Convoy there is a Support Element that includes a Convoy Support vehicle, a recovery vehicle and a coach. The AWE provides a Deputy Convoy Safety Officer who is responsible for this element.

They travel up from the Atomic Weapons Establishment multiple times a year because the warheads have to constantly be refurbished.
