Battlemasters manage all of the events at the DBBL and must have master communications capability. To realize this capability, the ASTi model is configured to give all of the Battlemaster stations the ability to:

• Communicate with any simulated FM radio net in the exercise
• Talk hands-free on a local intercom with the Observers at the Battlemaster station
• Speak to all operator positions in the exercise using a public address network intercom. The Battlemaster's PA intercom has a master over-ride feature, whereby all other radio and intercom communications in the exercise are muted while the Battlemaster is talking.
