In C&C, there the guys that sound like complete nerds and are used to repair buildings(not your buildings, public buildings, like the kind you stock with GI's or conscipts). They are most usefull when loaded into an IFV and stationed near your frontline.
Moody, God Complex, Think they are intelligent due to the vast experience in technology (3 to 5 years), over weight, some exotic ones have long hair and pony tails (only transexual men have pony tails), anti social, and on the rag 24/7. Usually Grumpy. Very upset about not being able to pick up the hot girl in college, and really pissed because they dont make much money and could have spent all that time drinking in college instead of programing with the Korean exchange student 'shwang balz'
one of my engineer introduces him self as a senior research scientist and has a vast history since the very beginning of network security... and he is 27.
A glorified custodian or handy-man. They have to be called an engineer, because it is more politically correct than being called a garbage man, janitor or plumber.
I'm sorry, but a waste management engineer is a garbage man. And a senior building engineer unclogs toilets and cleans the gum off of tables in the food court.
