Warhammer 40,000 (9th Edition): Space Marines - Primaris Techmarine

Primaris Techmarines stride selflessly through oncoming fire to soothe the machine spirits of wounded war engines, deftly peeling back damaged armour plates to repair burnt-out cabling and bending warped panels back into shape with their servo-arms and mechadendrites.

Techmarines specialise in repairing tanks and war machines, so if you favour armoured warfare, never leave home without a Techmarine or two in order to keep them in tip-top shape!
