NAM meaning in Military and Defence ?

The National Army Museum is the British Army's central museum. It is located in the Chelsea district of central London, adjacent to the Royal Hospital Chelsea, the home of the "Chelsea Pensioners". The museum is a non-departmental public body. It is usually open to the public from 10:00am to 5:30pm, except on 25–26 December and 1 January. Admission is free.

Having reopened in March 2017 following a major £23.75 million re-development project including £11.5m from the Heritage Lottery Fund, the museum houses five galleries that cover British military history from the English Civil War up to modern day.

This remit for the overall history of British land forces contrasts with those of other military museums in the United Kingdom concentrating on the history of individual corps and regiments of the British Army. It also differs from the subject matter of the Imperial War Museum, another national museum in London, which has a wider remit of theme (war experiences of British civilians and military personnel from all three services) but a narrower remit of time (after 1914).
