Hull Front, Lower 45
Hull Sides, Upper 45, 60
Hull Sides, Lower 45
Hull Rear 30, 47, 45
Hull Top 20-23
Hull Bottom 18, 20, 22
Turret Front 55, 90, 45-75
Turret Sides 55, 75
Turret Rear 50, 60, 75
Turret Top 20
Now it does not give angle of slope so those are realy better than they seam.
The realy important figures are the Top Armor ones, with top armor that thick(which is almost the same as the Tigers 25mm) they would be mostly imune from 50cal strafing.
Personaly my only objection the the T34 over the Sherman is the lack of an AA gun, the T 34 is such a better tank, i would realy like to see it over the Sherman, howeaver in AH whear the Plane GV interface is kinda unrealistic the lack of an AA MG might be a bad thing.
