The expression ""les CRS"" refers to the whole force. The feminine singular ""une CRS"" means a company (the noun "compagnie" is feminine), but the masculine singular ""un CRS"" is often used to means "a CRS man"; the press and laypeople frequently use "CRS" to mean any policeman in riot gear and wearing a helmet, whether he is a true CRS or a policeman or a "gendarme mobile". The form ""trois CRS"" in theory means three companies, but is often used to mean three men.
