With the invasion of Europe (D Day), fighter-bombers began a new direct support role, operating with the assistance of radio-equipped FACs on the ground with the supported formations. Allied tanks were emblazoned with a new white star on their turret tops. Cerise and yellow signal panels were provided to the 3rd Army troops. At least 10 tanks in every armored division were fitted with VHF sets to contact aircraft overhead.Rowley, pp. 3 - 4. Fighter bombers were on call from "Cab Ranks", orbiting points close to the forward edge of the battle area. Although already briefed for a target, the fighter-bombers would first await a call to strike an immediately pressing target. From these Cab Ranks, the FACs could very quickly call on air support for any targets of opportunity or threats to the troops in their area, with uncalled upon aircraft striking their briefed target. These ground FACs operated from White Scout Cars or Half Tracks (and later tanks) equipped with a wide range of radio sets for both ground to air and ground to ground communications. Airborne FACs were supplied from the Air Observation Post Squadrons  of the RAF  .Gooderson, p. 29.
