TECHNICAL

The term "Technical" or "Techie" to refer to small improvised fighting vehicles is centuries old, it's origin uncertain. Some linguists believe it dates back to Old Terra. But that's not important right now.

What you need to know is that these are small civilian vehicles with simple anti-tank weapons mounted on them. Going up against a mech in such a thing is suicidal, but in many parts of the periphery they fill out the mechanized portions of local militia. Many are also of course used by various pirates, upstart petty dictators, and anyone trying to pass themselves off as representing Law and Order.
