The Militia were part-timers, equivalent to today's Territorial Forces.
Men would volunteer and undertake basic training for several months at an army depot. Thereafter, they would return to civilian life, but report for regular periods of military training (usually on the weapons ranges) and an annual two-week training camp. In return, they would receive military pay and a financial retainer, a useful addition to their civilian wage. Of course, many saw the annual camp as the equivalent of a paid holiday. The militia thus appealed to agricultural labourers, colliers and the like, men in casual occupations, who could leave their civilian job and pick it up again.
