If you're referring to reversions made on Battle of Kursk, that is not vandalism.   doesn't agree with your changes, and has given some reasons for this in the edit summary made, which you can see from the article's page history.  You should be discussing the changes and asking why he or she reverted them, not making accusations of vandalism as you did at User talk:Dapi89#vandalizm.  All users should try to assume good faith, so please have a discussion with the user and try to reach a consensus.  Please let me know if you have any more questions.  Thanks!
