I think Cechs Zbrojovka(Zbrojovka was in big number in NDH Army)
MP 41(Very popular like officers kit in Ustaha unit,was bought in Austria)
About 3.HOS division(very hard to find anything because it was 1944/45)
"Croatian third division was located in Vinkovcima.It was created in December 1944 from 8 hunting(on german Jager-Brigade) Corps (formerly the 3rd hunting Brigade from Vinkovci, composition of 5th and 8th hunting Regiment, the first involved with three, the other with two battalions) II. Ustasha Corps (famous old Brigade, commanded by Colonel Ustasha Stir, then had four battalions), XIII. Ustasha Corps (later Brigade of four battalions of which two were stationary battalion called "Ðakovo" and "Zupanja"), VII. artillery assembly (formerly part of the 3rd hunting Corps) and one batteries II. Ustasha Corps.Division had a total of eight Ustasha Battalion and five hunting battalion and had 7500 men at beginnning .Division was commanded by General Stephen Mifek.It was one of the more powerful and better-equipped divisions, which, immediately after its establishment, took part in the defense of Srmium front .Parts of divisions were located spaced from Osijek to Sava River near Lipovca.That part on the first line of defense, between Lipovca and Save, was a major part of division.Part of division was set to a different defensive line, part in city Osijek and division headquarters in Vinkovcima.When 12 April 1945 front was broken, with part of which was held by 41 Germany "fortress" Division (units of mixed composition with German personnel of older vintages, and partly with exotic formations, composed of members of the Caucasian peoples, the Arabs and Hindus) had to withdraw and third Croatian division.In several occasions had provided resistance to the advancing Yugoslav communist forces, but the most famous is then when ten days, between 16 and 26 April 1945, held a Veliku kopaonicu , this allowing the withdrawal of axial forces from Bosne. The historians on several occasions mentioned bravely holding members of the Division, particularly the battle in which Colonel Styra near Valpova "fight and broke one Russian strong regiment" .Then division retreat westward and 26th April set in part Zvonimirova defense line, between Ban's ravines and Novske.After few days continue to retreat to Zagreb.Meanwhile partisans went to Zagreb, so part of the division remained isolated in the woods near the village Nartski Novaki, south of Long Sela.Domobran part of the officer corps decided to surrender, and the Ustasha did not want to give up, so Colonel Styra managed to get to Austria."
About uniforms i taught that officiers can be with black/dark green Ustaha uniforms and one/two different tip of Domobran(home guard) uniforms.
