Short story:
The skill "Command Vox Range" has no effect whatsoever. (game version 1.4.2b2-14263 "public_test")


Long story:
I was curious to find out at what distance, exactly, Sergeants and Battle Heroes support their fellow Terminators. That resulted in two particular pieces of information:

a)
The command area is not a circle. It is a square. Just like the range of Force Barrier. That actually came as a suprise to me. One would think someone had bothered to mention that in the community guides section.

b)
- Sergeant without Command Vox Range skill has a command range of 9, resulting in a square of 19*19 tiles. (Tested with lvl I Ultramarines.)
- Sergeant with Command Vox Range skill has a command range of 9. (Tested with lvl VII Ultramarines.)
- Battle Hero has a command range of 5 (11*11 tiles).
