Looks like harmless fun. It was stupid to videotape and even more stupid to release the public.
If I were their CO, I'd tell them "Knock it Off - thats 'yellow-light' behavior".
That kind of 'fun' has the potential to get out of hand - though nothing I saw was overtly over-the-line. Again, tell them to Knock it off, and perhaps find them some busiwork for a while to get them doing something else.
