Character specialties for better interactivity

[SwissArmy (DayZ) 5]

This mod is a lot of fun but lacks some complexity which would affect player behavior.

Why not add some complexity by assigning specializations to characters? For example, in Arma II it is possible to limit more complex medical undertakings to medics. Why not assign this specialization randomly upon spawning? Nothing visual would show that someone is a 'medic/doctor', so perhaps other players wouldn't be so keen on this becoming a PvP murdering free for all.

There are a number of other important specializations that could be assigned: examples are mechanic (fix vehicles), gunsmith (fix weapons), electronics specialist (fix radios), etc etc Without these specialties, a group cannot get by for too long. For the moment, it's too easy to pick up working items or repair items to use by anyone.
