Technically a "component repair company". Basically if you break it, they can fix it.
To be fair here they do seem to just be going "send me everyone!" so it's not clear any of these guys have the kit they'd need to do a job beyond stand around with a rifle. So their unit designation may be effectively meaningless... at the moment. If they send those guys their tools it means they're parked in for a siege.
Sorry if this is a stupid question, but what is a field repair unit?
