Escalators don't break, they just become stairs.
So in Halo 4, I know each specializations come with specific armor, abilities, and skins.
What I'm wondering is, when you go through a specialization "path", can I only use the armor itself and the ability while using this class (like a 1 time use thing), or can I use it while using other specializations? Example: Using the pioneer's armor ability while an operator.
