The navy minister Frank Judd became the guest of the army in Portsmouth.
Mr Judd visited the Portsmouth Detachment 43 Command Workshop REME, at Hilsea Lines, to meet the men working at the establishment and for a briefing on the work done there.
But he also got the feel of riding a motorbike.
Although it is one of the last army units in Portsmouth, the workshops in the establishment repair many types of army equipment, from small compasses and radio sets to 30-ton bridge-carrying trailers.
The detachment was established in 1964 and was responsible for the recovery and repair of vehicles, like the motorbike pictured, within the area between Portsmouth, Southampton, Winchester, Chichester and the Isle of Wight.
Among the items seen by Mr Judd was a complete field operating theatre capable of being transported by air to a battlefield.
Mr Judd said: ‘As the navy minister, I was particularly interested to see how the army operates and to make comparisons. I was very impressed.’
