(Answered) Advanced determining critical hits and physical attacks

[Kharim]

Question is simple: do battlemech melee weapons use advanced tables for critical hits?
On page 74 of TacOps it says that when internal structure takes a hit from a weapon attack one should roll on the advanced table. Is a hatchet a weapon or equipment?
For further consideration, what happens when internal structure gets hit by kick or punch? Is it treated as a weapon attack?

One more thing, some physical attack when using TSM generate huge damage values- Berserker C3 can hit one location for 40
damage. Would modifier in Advanced Table be only +4?

Change "weapon attack" to "attack" to cover everything.

Yes, the modifier for a 40-point damage attack would still be only +4.

Thanks Xotl!
