Looking for a movie I saw on TV back in the early 70s. I’m not sure how old the movie was. Could have been from the 60s? All I remember is a little boy about 10 or a bit younger climbing up onto a military tank. The soldier that was in it was half out of the tank and hit the kid across his head with the butt of his rifle. I don’t know what country they were in or anything else about it. It was in English.
