3rd Cavalry Regiment - Badges and Insignia 
 

The badge is of a Black Scorpion encased by a wreath with the tail swung up as if to strike placed over a inverted boomerang which has the unit motto RESOLUTE and is finished in gunmetal colour to reflect that it had been designed and chosen in a combat area.

The badge was designed by Lieutenant General John Grey, AO (retired) and assisted by Charles Gaunt and Colonel Roger Kershaw (retired) both whom where adjutants in succession during Lieutenant General Greys time in Vietnam. It was chosen as the Symbol of the 3rd Cavalry Regiment as it had already been adopted informally and painted on the side of all M113A1 vehicles with the Squadron.

The reason it was chosen was due to the prolific Black Scorpions crucial time in battle and to this day that reputation is maintained. The Queen approved the Scorpion Badge in 1972 and it took until 1977-78 before the Regiment was badged correctly. Up until that time the 3rd Cavalry Regiment wore the Corps Badge, except for the initial period in 27th May 1965 - 14th September 1965 when the 4th/19th Prince of Wales Light Horse badge was worn.
