Random question, but would the Republic ensure everyone going into the field had some sort of radio or comm system so that everyone could stay in touch with each other?

The commo net on a planet like Gthrak stinks and the Mandos intentionally sabotaged satcom to prevent that. Only a few characters would have actual radios that would get them in contact with the fleet. Everyone else has short range jobs and no, communication isn't assured in a very dense jungle.
