Tactics
The proportion of Pathfinder aircraft to Main Force bombers could vary according to the difficulty and location of the assigned target; 1 to 15 was common, though it could be as low as 1 to 3. By the start of 1944, the bulk of Bomber Command was bombing within 3 miles of the PFF indicators; an appreciable improvement in accuracy since 1942. The success or failure of a raid now largely depended on the Pathfinder's marker placement and how successfully further marking was corrected.
