Roger Federer advanced with brute force today at Wimbledon as he used what looked to be a Russian T-90 tank (bottom center) to defeat opponent Philipp Kohlschreiber (top left, terrified). It appears that Federer found a loophole in the tennis tournament’s rules that don’t disallow certain post-Soviet tanks from being used to advance on the field of play. Officials are holding an emergency meeting at this time to discuss whether or not it is too late to amend the tank rules while the tournament is in play.
