The tier 4 Russian premium light tank Valentine II is very similar to its British peer the Valentine.  Both share great armor for a light tank and sacrifice speed/firepower to have above average armor.  The armor of the Valentine II has very thick armor in all the right places and where to armor gets thin it is usually highly angled which gives it great armor across the front, side, and rear.  This weak spot guide will show you the best and worst places to shoot a Valentine.
