First of all for the soldiers, every soldier knows hand to hand combat, especially elite units. And assassins are all about stealth, the foundation of stealth is blending in, whether be it in ancient times or in modern(like that blonde assassin that helps you escape in assassin's creed 3? I think...) they always find a way to blend in and they can also use ranged weapons as being an assassin in modern times would require the use of snipers (duh). In what time would this take place? Modern? Or past times in the assassin's creed timeline of the 1,2,3 etc etc which game? And we need to have a location (besides time), and which city)in which game) do we take as our reference/starting point? What weapons and equipment do we get?
P.S-One more thing, I don't think i'll be part of this RP, everytime I see all the great Ubisoft games that I haven't played makes me cry in a corner(Q_Q).
