I have thought about using them to exband the range of the C2 link,but it seems do not work well.For instsnce,my co team have several mortars under direct control,and a xo team.I tried to put my co team into firing line to call for mortar supporting fire,and left my xo team just besides my mortars,cuz I noticed that the xo team has radio.I guessed the mortars would be ready to be called,but when my co team was far away,they were just out of contact...why?Doesn't the radio work?seems that the xo team cannot be considered as a C2 link point as the HQ team does..
