During the campaign from Lika to Serbia, the division's units were filled with new fighters, but as a large number of fighters were killed, the division didn't grow in numbers. At the end of January 1944, there were 3,336 fighters in the combat, while in mid-February there were 3,518 fighters. In May 1944, just before the Operation Rösselsprung, the division had 3,667 fighters, and after heavy fighting with German paratroopers on May 25 and 26, the number of fighters decreased for 156 - 49 were killed, 73 wounded. and 34 missing. In the fighting during the Drvar operation, as well as in the fighting during the forty-day march from Glamoč to Priboj the 6th Lika Division lost more than 1/3 of its soldiers, so in September 1944 it arrived on Zlatibor with only about 2,400 fighters. After arriving in Serbia, in the period from the liberation of Valjevo to the beginning of the Belgrade operation, there was an influx of a large number of new fighters into the division so the division on 9 October 1944 had over 5,600 fighters. At the end of November 1944, before the division withdrew from the Syrmian Front, it had a total of 5,992 fighters including many fighters who had recently arrived. Along with the recruitment of new fighters, hundreds of old fighters and officers were withdrawn from the division, who were sent as command staff to newly formed units and institutions. According to some data, from mid-September 1944 to the beginning of February 1945, a total of 520 old fighters were reassigned.
