Due to the hostile winters, BATUS conducts training from May to October each year. This normally consists of four to six battle groups (BGs) each exercising for around 24 days each, supported by the BATUS permanent and temporary staff and a dedicated enemy (traditionally provided by a single nominated regiment). There are relatively few servicemen permanently posted to BATUS (229 as of 2019, along with 250 dependent children), but their numbers are significantly increased by temporary staff who form the bulk of form the Operations Group (Ops Gp) who design and deliver the most complex live fire and simulated fully instrumented training for Armoured, Infantry and Strike Battlegroups. This, as well a large proportion of the camp based supporting organisations, including a dedicated logistics squadron and a REME workshop. Permanent postings to BATUS last two years. French-speaking local actors are often hired for exercises, to give soldiers experience of working with non-English speaking civilians.
