The Support Vehicle Armor Table on page 134 includes a footnote indicating that "At Tech Ratings E and F, BAR 10 Armor occupies slot space equal to that of Inner Sphere and Clan Ferro-Fibrous Armor types (respectively)." Is this supposed to be 14 / 7 slots, as for mechs (page 56), or 2 / 1 slots, as for Combat Vehicles (page 105)? The latter seems more reasonable in terms of actually fitting into a SV, but SVs generally use slot numbers equal to those for mechs for other items (see equipment tables starting on page 341).
Either case also somewhat contradicts the heading on page 134, "Space: Under these rules, no armor type available to Support Vehicles reduces their equipment slot space.", although this could be taken to indicate that the CV item slot reductions do not apply, further hinting that mech slot numbers should be used.
I will note that this came up due to using the mech-FF armor numbers rendering several canon SVs from TRO:Vehicle Annex invalid as built (not that some others aren't already ...)
