Works well for 40K. Not in epic.

The unit composition? Sure. Not allways.
But the names?

Examples? Here:
Armoured Mobile Hunter Cadre/Hammerhead Support Group = Armoured Interdiction Cadre

Battlesuit Cadre = Farstrike Battlesuit Force

Fire Warrior Cadre + Defilfishes = Fire Warrior Counter Strike

Pathfinder Support Group = "Mirage" Long Range Infiltration Unit

Recon Skimmer Support Group (if consisting mainly of Piranahs)= Firestream Piranha Wing

Stealth Support Group = Nighthunter Stealth Group
