Elysians, no one can withstand a hard and fast attack,
Situation one: attacking a fortress, reliance on stationary interceptor turrets to do quite a bit of the fighting, lighting strike across the walls in Valkyries, and catch the defenders off guard by the speed of the attack.
Situation two: attacking an armoured convoy, again, Valkyries screaming round and round, most heavy weapons on tanks couldn't rotate fast enough to hit them, while Vendettas could just blow them to hell with Lascannons.
Situation three: attacking an all infantry force, attack one flank, as the army swivels to bring its full might to bear, just hop in the Valks, and attack again from another flank.
Also they join voluntarily rather than being forced to like in other guard recruiting worlds, and they're homeworld is on a vital trade route, so they can afford due to the economics of being on a trade route, to give their soldiers the very best equipmet available.
Also I like having a army that stands out from all the Cadians at my local GW
