Were you ever stationed in Germany? When I was stationed there 20+ years ago, we had tens of thousands more troops, vehicles, and airplanes. I don't recall any successful attempt to wipe out a smaller facility, to include the old Nike-Hercules batteries that were located throughout West Germany. For your info, these units were nuclear capable, and therefore a much more lucrative target for a terrorist than an infantry battalion.
I recall many alerts and warnings of Baader-Meinhof gang activity, but their success was limited at best.
There will be plenty of safeguards put in place, to ensure proper dispersal of personnel, equipment, and material.
I have never been stationed in Germany. However, the enemy we face today is a lot less rational than the Soviets. The way I look at this situation is from the perspective of the aircraft at Pearl Harbor being parked in the open and grouped together so they were more easy to protect against sabotage. The end result was the loss of alot of aircraft by very few munitions. I also look at it from the perspective of closing naval bases and concentrating fleet assets in fewer areas. The Spanish learned the hard way in Plymout Harbor about grouping their fleet together for protection. To me, this is a huge tactical mistake.
