 Browndown Camp at the site was a barracks facility with an attached assault course and a 25-metre small arms firing range.The fort itself was utilized in some defensive tactical training, but was too small for use in OBUA (Operations in Built Up Areas) exercises.The Camp was used by Her Majesty's Naval Service's Royal Marines' Small Arms Corps from 1922 to 1959; the British Army's South East District command as a Minor Training Facility in 1961, and by 121 Weekend Training Centre up to the mid-1970s.
