Currently, the only doctor profile available in Sectorials is the 112.
The Kazak doktor costs 1 point more than the 112 and he sports a rifle instead of a light shotgun. He also has 1
ARM compared to 0 but he loses the
CCW, 1 PH and the
CCW.
In terms of healing capacity, they are both at
WIP 13 so are both as good for this (or bad =P )
And the reason why it currently has so few USAriadnan models is because they are focusing on the sectorials that are currently out (Caledonian and Merovingian)
I suppose that the Russian and the American sectorials will be fleshed out next (let's hope so

)
