Great job Jackie, and good tips.
Two things: I don't believe it's possible in NW to chamber a normal bayonet stab with an overhead bayonet stab as suggested, and you mentioned when doing held rechambers not to hold for a short time or it will be rechambered like normal, but maybe add also not to hold it for too long or you are vulnerable to the enemy's intended rechamber stab.
Other than that, excellent melee guide.
