Losses grew in the face of a more aggressive enemy flying newer aircraft. The last major action was on 17 January 1943: 25 C.200s strafed enemy troops in the Millerovo area. The aviation of the ARMIR was withdrawn on 18 January, bringing 30 C.200 and nine C.202 fighters back to Italy and leaving 15 unserviceable aircraft behind. A total of 66 Italian aircraft had been lost on Eastern Front – against, according to official figures, 88 victories claimed during 17 months of action in that theatre.
