Its useful because it allows you to field 3 small squads of 5, two squads of uneven numbers (7 and 8 or 10 and 5 and so forth) or if minimum size is lower (say 3 or 4) you cold field 3 small squads, which can be useful when trying to out manuever the enemy.

Hi, a bit of clarity regarding heroes.

Named ones will be limited to 1 per battlefield e.g. Max, angelika, immortal

Others heroes could be classed as repeatable, e.g. The Everassurs

Others though named fluff wise could be repeated, dr Diana who is a clone

You can also design your own so could play max Steiner and your own character who uses the same model

Heroes can be the commander, so your army could be lead by THE immortal and have any combination of Everassurs and Dianas

aha i thout you could hawe multipla immortals
