The Blue Sun Mod

yes you can send troops to other sectors.. it is only a fraction of the troops that are available tho.. (with 30 militiamen in the radio hill sector i was able to send out a unit of 10 men from radio hill.. less on other sectors)

you can actually go to the sector you sent em to and wait for their arrival.
you can then fight alongside them or just watch your blue guys fight the enemy...

after dispatching a unit of men from a sector there seems to be a cooldown period until it works again. i have no idea how long it takes.
you don't have to be around for the battle to take place... but since the number of men you can send out is rather limited, and it's not really possible to combine the forces of several sectors... your chances to win will be quite small if you don't.

since i'm not up to date i'm not even sure if R@S has actually released a version with the radio publicly...

it requires the reloaded map pack to work.
