Just a quick confirmation (I think): per the rules for non-fusion BattleMechs, they suffer "the same movement, terrain, and environment restrictions as an IndustrialMech mounting the same engine type" (Tactical Operations errata to p. 308). For specifically internal combustion powered BattleMechs, that would include the need for an extra Piloting Skill Roll after a fall to avoid having the engine stall out (Total Warfare p. 59), correct?
