What do you mean by "from beginning to end"? Soldiers who were in the armed forces on June 22nd 1941 who were still alive and still in the armed forces on May 9th 1945? Also, do you want to know only about enlisted men, or are you counting officers? The answer in either case is "yes, plenty", but it's easier to find examples of officers. Just off the top of my head, Georgy Zhukov served through the entire war.
