I have some sympathy as co-operative military actions are just the same. May I suggest that if the problem that you have are players, phone is far more effective than email.
If the problem is system orientated, get the player id's of those involved and then email or phone PD directly outlining what you are trying to achieve and the problems that you are experiencing. I have found them extremely helpful in the past.
