There's an interesting reason for this. The US Army has spent, literally, hundreds of millions of dollars in the last fifty years doing this kind of reaching out to the communities in the parts of Germany units were stationed in. The reason is that countless German farms, fields and other propety were very often damaged by units manouvering during training, traffic disrupted, noise levels raised, etc., and millions were paid out as compensation to farmers and landowners.
This gave Army units a very strong incentive to mitigate bad press by co-operating with locals, fostering good will and making nice by doing this kind of thing.
