Texture coordinates are flipped on sniper left pauldron for 2nd choice. When equipping a symbol (such as the Space Wolves), the head should point forward. The symbol is correct in 4 of 5 pauldrons, but the 2nd pauldron the wolf head faces backwards. As shown in the equipment preview and shoulder on the below screenshots.

Below is the correct direction. 4 of the the 5 pauldrons (excluding Deathwatch) face forward. Wolves face forward towards battle.

Below is the incorrect direction. Only 1 of the 4 pauldrons (excluding Deathwatch) face backwards.
