What is an OR and /or what are ORs?
OR stands for Other Ranks. It is sometimes used in the context of ‘Officers and Other Ranks’ but on many occasions it refers to soldiers below the rank of Sergeant. There are Officers, Warrant Officers, Senior Non Commissioned Officers (Staff Sergeants and Sergeants) and ‘Other Ranks’ (Corporals, Lance Corporals and privates soldiers). If you want a beer in the Army you will go to the Officers Mess, the Sergeants Mess or the ORs Canteen, depending on your rank.
