It must be borne in mind, that a substantial majority of rifle clubs of whatever type and a significant number of clay shoots are run on a totally voluntary basis. Running the club is done in members' spare time. Along with the straightforward tasks such as cutting the grass (don't forget to get the lawnmower serviced), sweeping the indoor range (the head has come off the broom again) there are a multitude of administrative tasks such as keeping membership lists up to date, ensuring subscriptions are paid and if it's Home Office Approved club a long list of additional things to comply with. The essential task have to be done, but sometimes when people are on holiday or away for work reasons or due to illness, if its' not essential it may not be done for a week or two. Below is a list; not comprehensive; of typical club officer roles:

Chair - Chief operating officer of the club
