Sam is more on combat (so it is normal to get spotted by enemies when you play as him) Blade Wolf is more on stealth ops and Raiden is a balance of both
I was always wondering why Bladewolf loses to both Raiden and Sam if he's supposed to be a better breed than the other LQ-84i. Looking at how you fight makes me realized that he was probably better suited for stealth missions. I mean, real life dogs are good for scouting after all.
LQ-84i is the model number of bladewolf and the official "name" Desperado used to refer to it. The name bladewolf would later be given to him by Raiden and maverick. AWOL is the military term for leaving or going absent without official permission, albeit it is also used when you leave without said permission but without intent to actually desert (which May be foreshadowing to the ending of the dlc) So basically mistral was telling them "if you see this bitch it shouldnt be there" probably so they can try fight and recapture/kill it
I tried using bullet parry strat for Khamsin (If you are far away Khamsin will lower his axe and start dashing towards you similary to his execute prompt. In this time gun mounted bellow him will shoot at you). Not recommended. You have small frame window to parry exactly one bullet to keep full hp and deal 10%. Couldn't do it consistently. Once per try max, no more.
Did you know that you can parry khamsin from afar without taking damage from his bullets? It just takes jumping + defensive offensive at just the right time to then parry
