I have been reading through the construction rules for protomechs and their ultraheavy counterparts, and I find I have a question.
In the weapon and equipment table in tech manual it indicates that several weapons are unavailable to protomechs (they have an N/A in the column that indicates how many spaces they take up). However I cannot find anything in the actual text of the protomech design rules that indicates any weapons (aside for the special rules for missiles) are actually prohibited to protomechs. Coincidentally, aside from missiles and inner sphere weapons, all those weapons that are listed as N/A for protomechs wouldn't fit on a standard protomech anyway.
Jump forward to Wars of Reaving, and now we have ultraheavy protomechs. Once again, there's no mention in the text of any specific limitations on what weapons can and cannot be mounted on an ultraheavy protomech, aside from the special missile rules. What's more, many of the weapons that have the N/A tag in tech manual are actually light enough to fit on ultraheavy protomechs. One of those weapons (the Plasma Cannon as per errata) is actually mounted on an ultraheavy protomech in Wars of Reaving.
This of course raises the spectre of ultra heavy protomechs walking around with ER PPCs, LB10-Xs, or even small HAGs. So my question is thus: are certain weapons inherently prohibited from use on a protomech, or (outside of the special rules for missiles) might a protomech make use of any weapon it has the tonnage to carry?
