No, all of those characters themselves aren't real but some may be based off of real stories or urban legend type deals. I know the German doctor guy( I can't recall his name) is indirectly based off of Dr. Mengele, a German doctor at the Aushwitz concentration camp.
If you mean Modern Warfare 2, then yes. If you mean World at War, then, obviously, no.
Yes, in Call of Duty: MW3
"Nikolai's Vodka"
nikolai belinski
All of them
Nikolai dempsey takeo richtoven samatha
First, Why does it matter? But second, He's forty.
Yes, along with Price and Nikolai.
get real call of duty
No, but many of the call of duty games made by treyarch are based on real events and real people.
If by call of duty reflex you mean call of duty: modern warfare 2 then no. Well, i guess its implied that he doesnt because price patches him up and they escape in nikolai's helo.
There is no real answer but I prefer Call of Duty
Foley, Ramirez, Dunn, McTavish, Price, Nikolai and Makarov
