in the U.S. army commo jobs are pretty tight. You can do highspeed "lets go for adventure" or you can play it chill and do very little.
I'm trained to correct software, and point out hardware problems with common radios, computers, tactical satelite communications including portable dishes, computer router configuration(cisco) creating Ip addresses, assigning them to multiple machines, creating networks (Lan, Man, Wan), and a few other things. Stuff the Regular army uses. Got a chance to train with some of the commo equipment in special ops but very limited time spent with that.
I'm just about to go to my 1st duty station after almost 11months of various training...been very interesting so far, and met some good people, and have done some fun things, such as (airborne) training.
not sure what the job parameters are in your countries army but sounds like it could be similiar to what I do.
Do you have a website that talks about the job?
