I would invite you to tea Commander, but, there is simply no time.  My apologies.  Here is the situation. The Germans have held the fortress city of Metz for two months against American attacks, and now the Yanks have requested our help.  Our troops must  smash Jerry's resistance, then punch through the Maginot Line. Metz is the site of the German training schools for officers and NCOs, so you can expect a tough fight.  This mission is crucial, Commander.  You must act decisively.
