fire up ability is only on one unit, one! and its not even like ooorah when you dont get any penalties after using it.
Rangers.
Paras.
Whole britblob could be fired up by officer.
And oorah doesn't give you suppression immunity, so I can't see how can you compare them.
I like that some things never change, like you acting like you have rabies and being as clueless as ever about stuff you talk about.
