[4] Perhinek was a military adviser[10] and one of the closest associates of Draža Mihailović when he was a commander of the 39th Infantry Regiment in Celje, modern day Slovenia.

[4] In June 1941 Perhinek organized a conference of the former military officers of the Yugoslav Army in Berane, including Cemović and Joksimović.

[4] Based on the instructions of the representatives of civic political parties from Berane received in September 1941, Perhinek and Lieutenant Mirko Kuklić made a successful journey to Mihailović's headquarter on Ravna Gora in the first half of October 1941.

[21] On 15 September 1942 Perhinek attended the conference of the commanders of corps, brigades and districts from the territory under control of the Lim-Sandžak Chetnik Detachment held in Kolašin.

[22] In October 1942, "Green" member of collaborationist committee Vojislav Nenadović tried to replace Chetnik president Blažo Đukanović.

While he got majority against Đukanović in the committee, Draža Mihailović and Pavle Đurišić convinced Governor of Montenegro Alessandro Pirzio Biroli not to dismiss.

[23] As an envoy of Chetnik supreme command, Perhinek participated at the so-called Second Youth Conference held on 4 December 1942 in Šahovići, Montenegro.

[8]: 285 Based on instructions of Draža Mihailović, Perhinek established the communication with Balli Kombëtar and leader of Albanian Catholics of northern Albania.

[26] In the middle of May 1943, prior to the formal commencement of Case Black and in its initial phases, around 2,000 men from Lim-Sandžak Chetnik Detachment (LSCD), including Đurišić, were captured by German forces.

With the approval of Perhinek, they recreated Chetnik organisation and new staff of LSCD and proposed Mihailović to appoint Lukačević as their commander.

[29] Mihailović accepted this proposal and Vojislav Lukačević succeeded Đurišić as the commander of the remaining men of the detachment and, accompanied by Perhinek,[20]: 300  came to Berane on 14 July 1943.

[34] Eventually Division Venezia joined Partisans who managed to capture Berane and gain significant advantage toward Chetniks in eastern Montenegro.

[35] In November 1943, after the failure of the Operation Balkanschlucht, around 300 Chetniks from Berane and Andrijevica led also by Perhinek retreated from Montenegro to mountains Javor and Golija in Serbia.

[36] Milan Nedić sent to Nova Varoš some of his units to support Chetniks from Sandžak and Montenegro, but they were prevented by the Germans to continue their advance.
