What makes up II(AC) Squadron's heraldic badge?
Why A.C?
The A.C stands for Army Co-operation and the squadron was given this title due to flying Army Co-operation sorties in the 1920s as part of the partition of Ireland.
Roundel
In the background the badge displays the RAF roundel. The roundel was introduced in 1914 to help identify British aircraft. Colours were chosen by reversing the French roundel of red and white with a blue centre.
Moto
The moto is "Hereward" which is from Hereward the Wake an anglo saxon leader who opposed the Norman Conquest. Hereward is an Old English name which means Army Guard.
Knot
The knot in the centre of the badge is the Wake Knot. This is from the Wake family crest who claim to be descended from Hereward the Wake.
