and major, and old positional ranks like 'squad leader', 'inspector', and 'director', some with several grades like 'senior' or 'junior'. The collar rank insignia was completely original and not based on military insignia. This system was largely reused by the GUGB in their special rank structure introduced in 1935, although with new rank insignia and Commissar-style ranks for top officers. New insignia were issued to GUGB in 1937 and to Militsiya in 1939. It was now based on collar rank patches of the Red Army and Internal Troops. Confusingly, the special NKVD rank system was left intact, so for example 'Captain of Militsiya/State Security was assigned the three-box insignia of an army Colonel (in the Red Army, this patch was reassigned to lieutenant colonel in September 1939, but the NKVD did not alter their insignia) and Major of Militsiya/State Security was mapped to one-romb insignia of Kombrig (a brigade commander) (which was abolished for commanding officers of the Red Army in May 1940). This created a great deal of inconsistency and tension between army and NKVD/NKGB officers. The NKVD rank system was streamlined in 1943 when imperial-style shoulder boards replaced the collar insignia patches. The ranks now copied those of the Soviet Army, with the exception of top officers starting with 'Senior Major' who were renamed Commissar of Militsiya 3rd, 2nd, and 1st rank, although they still wore army-style Major General, Lieutenant General and Colonel General shoulder boards. The GUGB/NKGB maintained their commissar ranks until 1945, and switched to equivalent General ranks after that. The Militsiya retained the commissar ranks until 1973. Some MVD officers had distinct ranks of General of the Internal Service of 1st, 2nd and 3rd rank; they were replaced with Major General, Lieutenant General and Colonel General in the 1970s. Ranks of militsiya are considered special ranks, not to be confused with military (all-forces) ranks, which are used by the internal troops of the MVD. All militsiya ranks have had the words "of militsiya" at the end, which are part of the rank name and not a descriptive addition.
