Pebbles, PA, if I might add to this debate... What you suggest would of course be hilarious. But keep in mind that PES downloaded from Google Play is not intended to be used in combat.
I mean if you insist, we won't say no to a purchase. But we would rather recommend a Mil version of PES that uses Personal Role Radios or Tactical Radios for communication purposes. Also a centralized server is a bad idea for a combat net. We prefer to use a self building mesh network on top of radios of your choice. And of course... If you do not trust your radios to provide a secure enough link, we can provide a AES256 encryption on top of the radio encryption and frequency hopping.
I hope this helps clear up the intended PES usage. Let me know if I can be of further assistance.
