A unique collaboration between British and German forces could be under threat when UK troops pull out of Germany in 2019.
The two forces use joint specialist skills to move military vehicles across rivers on what is known as an M3 Rig.
There are concerns this unique capability could be lost.
Sappers from 75 Engineer Regiment worked alongside the German Bundeswehr to build an 80-metre structure in order to display their skills to the visiting Commander Field Army Lt General Patrick Sanders and the Bundeswehr's Lt General Carsten Jacobson.
The Germany based engineers from 23 Amphibious Engineering troop, Reservists from 412 Amphibious Engineering Troop and their German Counterparts from 130 Pioneer Battalion are unique in their ability.
The M3 rigs move their display carefully across the Weser river, manoeuvring into position to create the bridge, and separating to two pieces, or ferries, to move vehicles from one side to the other.
The wheeled vehicles turn in to boats, which become a bridge, and then split to form those long ferries that can move at speed.
This collaboration and its unique capability could be under threat with the Army leaving Germany under the 2020 restructuring, but its future is certainly not yet decided.
