The Wavy Arrow





Soon after the 20th Engineers invaded North Africa on November 8, 1942, as part of Operation Torch, orders were given to delete unit identification markings from all vehicles and field locations. When Colonel Eugene Mead Caffey, the Regimental Commander of the 20th Engineer Combat Regiment, received this order, he declared, "Since Regimental operations on the Casablanca docks have earned us the very unjustified reputation as 'the biggest crooks in the Western Task Force,' it is only fitting that we adopt as our symbol a crooked or wavy arrow in Engineer red." Thus the Wavy Arrow was born.

The red wavy arrow has been used ever since to mark 20th Engineer equipment, to include during combat operations in Vietnam, Iraq, and Afghanistan, and at present-day Fort Hood.

In 2005, the 20th Engineer Battalion was relieved from assignment to the 1st Cavalry Division and disbanded. The battalion headquarters remained in place, and was redesignated the 1st Special Troops Battalion, 1st Brigade, 1st Cavalry Division--a brand new type of unit. When the Army's Institute of Heraldry designed a unit crest for the new organization, they included the wavy red arrow as one of the major heraldic elements to show linkage to the history of the 20th Engineers. The 20th Engineer Battalion was re-constituted a short time later under the 36th Engineer Brigade.
