The sticky for the Errata forum reads to me that if a potential errata involves even nominal rules ambiguity it belongs here.
PA is listed as tech rating all/D but all PA/BA armor is at least tech rating E. Is PA's rating in error or should standard (basic) armor's tech rating be lower?
BA jumpjets/jump packs are tech rating all/C, but both jump infantry and mech jumpjets are tech rating all/D. I can't imagine that BA jumpjets are really meant to be less complicated than both lighter infantry jumpjets and heavier mech jumpjets.
