The Defence Academy has opened a new leadership and management training centre in Shrivenham, near Swindon.
The academy is the higher education institute for the UK's defence sector.
The new training facility aims to produce future commanders and leaders for the armed forces. Educational courses will start running for senior military and Ministry of Defence (MoD) civilian personnel immediately.
Chief of the defence staff, air chief marshal Sir Jock Stirrup said: "This important new training facility will be an asset to the armed forces and the Ministry of Defence as we prepare our military and civilian leaders for the challenges of the future."
It is expected the facilities will also attract users from elsewhere in the MoD, other government departments and private companies.
