The Territorial Army has long lived with a Home Guard, "weekend warrior" image, but as the government moves to slash the number of regular troops, reserve forces will be playing an ever greater role.
For the past year, Wales This Week cameras have been following the fortunes of Welsh Reservists, from the TA's newest recruits to fully-fledged soldiers on the front line in Afghanistan.
Infantry recruits have nine weekends of preparatory training before going on a two-week course at Catterick in Yorkshire to complete their initial instruction. They then commit to a minimum of 27 training days a year and within little more than twelve months, could then be deployed to Afghanistan.
Inevitably, employers will come under increasing pressure to free up their staff for military duty.
Last week, the UK Government confirmed plans to recruit a further 10,000 part-time soldiers and rename the TA as the Army Reserve.
