Hi! you probably don't care about this information, but I think others will read it. To make everything work, we need to:
1 Put a voice for all units

2 create any object and enter it into it

this addAction ["<t color='#00FFFF'>Arsenal</t>", {["Open",true] spawn BIS_fnc_arsenal}]

3 start the game, find the combine's voice in the arsenal, and then press ~ and select any message and press enter, not the space bar (don't press the space bar because it creates some script errors), and that's it, you have the combine's voice and your squad speaks it

I don't know about others, but I solved my problem like this

UPD: errors are created due to
improved melee system addons

Thank you very much
