[edit]
When German forces used captured KV-1s, they were renamed as “Panzerkampfwagen KV-IA 753(r)”[40]
The Finnish forces had two KV-1s, nicknamed Klimi, a Model 1941 and Model 1942, both of which received minor upgrades in their service, and both of which survived the war.[41][42][43]
Romanian forces captured one KV-1 as of 1 November 1942 and one more in March 1944.[44].
future looks bleak
