Most General Staff officers are graduates of the Federal Armed Forces Command and General Staff Academy ("Führungsakademie") in Hamburg. General Staff officers are rotated through line commands to keep them familiar with everyday unit problems. General Staff officers are identified by crimson facings on their uniforms and by inserting "i. G." ("im Generalstabsdienst") after their rank. Less than four per cent of officers are members of the General Staff. There are five General Staff officers in each "Bundeswehr" division. At the headquarters of Allied Forces Central Europe in Brunssum Netherlands there are roughly one hundred German officers, but only seventeen are General Staff officers.
