I would like to introduce an addon that Le Culto and Johnson of the Blackwater France team have made:

It is an addon that allows Arma 2 to communicate with Teamspeak 3 to simulate realistic communications.

————- Here is the features list :

3D sound with everybody around you (friendly and ennemy)

Management of the power of voice (wishpering, talking, yelling)

Radio communications

short range and long range device
management of 300000 frequencies
realistic radio use (transmitting OR receiving, not both in the same time)

Possibilities of electronic warfare

goniometer
possibilities of scanning frequencies

————- What you need :

1) Arma 2
2) Teamspeak 3 client for windows (64bits or 32bits)
3) ACE mod (for long range radio device)
4) A little patience to configure the 3 keys needed
