2282 Borg: Hunter-Killer

In 2282 universe there're some changes in military.
Infantry splits to Infantry and Heavy Infantry (with power armours).
Borgs are something in between Mech (wich is classified as armour, while its so tough it's supposed to endure most attacks) and power armour. They're also classified as Hvy Inf, Borg has thic plating, but not strong enough to stand against tanks. It relies on mobility, seeks cover etc. Most Borgs are more mobile than infantry... but much more expensive.

This model is armoured below average. Squad of well led infantry may stand its charge, force it to flee or even destroy. Operators head, even in mask, is not protected well enough against heavier laser sniper riflers. But hunter-killers dont fight infantry, they're hunting mech, tanks and other borg.
This machine may make huge jumps, with its back mounted jet engines. Minnigun is used to weaken enemy, or fend off infantry. Sword may swing around breaking power armour... or make violent thrust to cut Mech knees, cripple tank or destroy other Borg. It's exteremaly mobile, runnig up to 180km/h, changing directions on 1m radius and jumping above enemies.
