Technicians are civilians with technical skills and are hired or forced to work with Brotherhood of Nod. They have little to no combat experience and only have pistols for their defence.
In Multiplayer they cost 350 credits to purchase and come equiped with a Pistol, 2 Timed C4 charges, 2 Remote C4, an Advanced repair gun charges and Proximity mines. This makes it the only Nod unit capable of destroying a structure outright independently of additional ammunition- assuming they can reach the Master Control Terminal and arm their explosives.
The Technician is the multiplayer equivilent of GDI 's Hotwire.
