In this narrated battle, I earned my “Ace Tanker” Mastery Achievement for the IS-4, the beefier of the two tier 10 Soviet heavy tanks in World of Tanks (WoT).
While the IS-4 has good overall armor, the front hull has a large weak spot, the Lower Front Glacis (LFG). The LFG of the IS-4 has effective armor of 209mm, which can be penetrated easily by most tier 9-10 tanks.
Due to the thickness of the IS-4’s side hull armor (160mm), you can angle the hull 35° to protect the LFG.
Note that when angling, you do decrease the effective armor of the Upper Front Side Hull (UFSH). Therefore, you’ll want to wiggle back and forth to protect the UFSH, as I did against the Foch TD’s 3rd shot.

This is the first of a series of “Ace Tanker” videos so I hope you enjoyed it!
Next up: the VK 36.01 (H), a tier 6 German medium tank.
