UDES 03
As promised, not every tank on this list is going to have the highest health pool or the thickest armor. The UDES 03, though it does have a respectably well-angled hull, is tough to destroy for a completely different reason.
This Swedish Tank Destroyer boasts an absolutely incredible camouflage rating. For a Tank Destroyer, being able to remain completely undetected is your greatest asset aside from raw firepower – which the UDES 03 also manages to offer in spades.
By knowing what skills to train first and what equipment to purchase, the UDES 03 is able to bring its concealment up to almost 70% when stationary and over 30% when mobile. So while the vehicle is extremely vulnerable to attack, the trouble is actually trying to find it in the first place.
