choosed that place because of 2 reasons:
1. While that area is not patrolled by your forces it can be patrolled by ours.
2. Main reason. We are only now trying to enter Rheinland and don't want to presss on you. But if you will accept this, we can construct base in some other place. And we already choosed place where to construct it.
New coordinates of base already sent by PM.
