A-Company, The Duke of Edinburgh‘s Company, First Battalion, The RCR
Right-of-Line of the Regiment. RCR‘s Canada‘s Senior Infantry Regiment. Order of Precedence within Infantry: ONE. Formed 21 December 1883 when the Infantry School was authorized. FYI below...for whomever gives a rats *** !
"Units of a regiment take senority according to the date of origin of the oldest unit of the regiment, e.g. Militia regiments having two or more battalions take precedence with the date of origin of the oldest battalion of the regiment of the Militia.
Units or Guards take precedence over other units in the infantry, regardless of the date of origin. Regular Force units take precedence over Reserve units.
The dates of organization assigned to regiments are those established by General Orders or parallel authority. Senority is based upon the date of origin as a regiment or battalion, not as local or independent companies of Militia, unless some other senority has been specifically authorized" p. 232.
