Der Spiegel Online has a very interesting piece on the German army's new found enthusiasm for air strikes and armed drones:
It was a summer's day in June 2009 when the German army in Afghanistan first used US Army drones in combat. With hindsight, some observers say that was the day the German military lost its innocence in Afghanistan. The firing of deadly rockets from drones on the orders of a German commander was part of the new reality of war in northern Afghanistan.The report indicates a pretty high degree of escalation of German involvement in the war -- a very touchy issue in that country where a strong majority disapprove of the war.

This might be due to rules for journalists which forbid reporting on such things, or it could be that Canadian forces don't call in air strikes or use armed drones.
Before that the Germans had only used US drones, lent out to them by the US military as part of the NATO mission in Afghanistan, to observe Taliban movements. They didn't take advantage of the drones' deadly Hellfire rockets. But on June 15 last year, Colonel Georg Klein pushed the red button for the first time.
