The case can also be made for a reactionary strike. By this I mean the bad guy has initiated an assualt against you and violated your personal space. This could be in the form of getting right up in your face, faking a punch, telling you he's going to kill you will reaching behind him (as in making it look like he's reaching for a weapon) and you initiate a strike to create distance and/or interrupt his intended action. For example, if I walk up to you while clenching my teeth and balling my hand into a fist and then flinch towards you as though I'm throwing a punch at you, you don't need to stand there and wait to see if I'm truly throwing a punch or just trying to intimidate you. Thus the reactionary strike; a strike that is a reaction to the received impulse of being attacked.
A reactionary strike could also take the form of a cover block that is also an offensive movement. For those familar with terms such as 'shield block', 'cow-catcher', 'chin jab', 'crazy monkey', 'elbow spear' etc they are movements designed to protect the 'command center' i.e. your head while doing something to the attacker in an attempt to eliminate or reduce further attack.

Just some additional thoughts for consideration.
