uses my armour formula and Thompson's F-Formula
Grant Palmer f-formula t/d = 0.0623 * mv^2/d^3 * f^2 cos^2 0 t = Armor Thickness (meters)C d = Projectile Diameter (meters) m = Projectile Mass (kilograms) v = Projectile Velocity (m/sec) θ = Angle of Impact (radians) F = F-Coefficient (dimensionless)
