The Prussian Landespolizei flag displayed at FOTW with the description "Banner of the Protection Police of Prussia" was not only used by Polizei (Police) units but also by Heer (Army) and Luftwaffe (Air Force) units formed when Landespolizei battalions were transferred to the Wehrmacht (Armed Forces) as whole units, for example the I Battalion of Infanterie-Regiment 77 (26. Infanterie-Division) or two battalions of Regiment General Göring (later I. / Fallschirmjäger Regiment 1).
