The enemy is operating German a/c types on the Rumanian front, partly with German markings.

1) Round the fuselage in front of the ailerons £Höhenflosse£ a ring 40 cm. wide.
2) Under the left wing, the entire wing depth a “V” open in the direction of flight with a 45º angle and a leg breadth of 25 cm. The legs of the open “V” are to be extended over the leading edge to a depth of 60 cm., so that recognition is also possible from above.
The prescribed identification is to be brought into use forthwith. Completion is to be reported by 25/9/0400 hrs. From then onwards up to 30 km. distance from the front “open fire” on all named a/c without the new marking (order follows).
Lw.Kdo. Südost is requested to associate itself with this regulation on the Rumanian front.
