Though General Verle talked a big game, he could not guarantee that the upcoming battle would proceed as straightforward as the battle simulation suggested.
There were more than enough examples in history where a numerically and qualitatively inferior force managed to overcome a superior opponent.
The Fridaymen possessed a defensive advantage and could count on the Kosic Ring as well as other local amenities to prop up their mech divisions.
In contrast, the Hex Federation and the Golden Skull Alliance had to dispatch their main force far away from friendly lines and deep into the space claimed by the Friday Colonies!
It was unrealistic for the Hexers to be able to provide any additional reinforcements or supplies over such an excruciatingly long distance.
