Jasta 18's Staffelfuhrer (also Jastaführer, Commanding officers) were:[2][3] A dozen flying aces served within its ranks, including Berthold, Hans Müller, Walter von Bülow-Bothkamp, Wilhelm Kühne, Paul Strähle, Harald Auffarth, Joseph Veltjens, and Johannes Klein.

[5] About this time, Leutnant der Reserve August Raben transferred in from Jasta 15 to take command on 14 March 1918.

The new unit livery for Raben's Jasta 18 began to appear by the end of April 1918,[6] and consisted of a white rear fuselage and all-white tail surfaces, with vermilion red forward of the cockpit and on the wings' upper surfaces, and usually left the bare wing panels' undersides unpainted, showing their printed lozenge camouflage.

[7] The squadron's main unit insignia consisted of a stenciled black raven, similar in appearance to what Raben himself had used on his own fighter aircraft while previously serving with Jagdstaffel 39, on just about all of the squadron's aircraft fuselage sides on the white rear area, with varying personal insignia added in black, usually along with the raven.

[10] By early autumn 1918, after the final move to Montingen, the aerial actions undertaken between the USAAS and the Luftstreitkräfte over the Battle of Saint-Mihiel pitted Jasta 18 against the macabre-marked USAAS' 13th Aero Squadron and their Grim Oscar-bearing SPAD XIII fighters, with the two units tangling a number of times from the St. Mihiel offensive onwards to the Armistice.
