From what I understand they did influence Battle Armour design, but more indirectly rather than directly.
A spiritual precursor rather than direct ancestor. Nighthawks allowed infantry a great deal of increased
survivability and gave them mobility close to what BattleMechs have.
Clan Elemental Battle Armour was the first true Battle Armour, and these have their origin with diving suits used by
Clan Goliath Scorpion for deep sea mining. The Wolves then got the idea to mount weapons and jump suits on the
diving suits so resulting in true Battle Armour.
EDIT: Am I correct in assuming Fury Teams were the Second SLDF equivalent of the Black Hearts? Supposed to do
all the nasty missions that were supposed to stay out of the limelight.
Or did they have a more mainstream role as an actual Battlefield infantry unit?
