The way that the upgrade sections read currently with wording like "up to two" and "replace one" sounds like those are limitations on the max number that can be upgraded. Contrast this with "replace any", which sounds like it is not limited.
As such, looking at the Jetpack Warriors and their upgrade groups A and G, am I reading correctly that one Jetpack Warrior can be given a special hammer from group A ("replace one CCW") and one Jetpack Warrior can be given a special hammer from group G ("replace one CCW"), but there is no way to give all the models in the squad special hammers, onepageanon? (I am trying to create a squad akin to Battle Brothers' Assault Brothers)
