Tower Shields is a technology in Age of Empires II: Definitive Edition that is unique to the Lithuanians and can be researched at the Castle once the Imperial Age is reached. Once researched, it gives the Spearman and Skirmisher line units +2 pierce armor.


Lithuanians don't have access to Plate Mail Armor, so Tower Shields is important for their Spearman line. With Tower Shields and all Blacksmith upgrades, Lithuanian Elite Skirmishers have the second highest pierce armor among non-siege units (10), matching the Elite Huskarl, the Elite Rattan Archer and the Inca Elite Eagle Warrior with Fabric Shields, only behind the Lithuanian Imperial Skirmisher (who the Lithuanians only have access to in team games with a Vietnamese ally), that has 11 pierce armor.

The technology should be treated as another Blacksmith upgrade. Considering its cost and usefulness, it should be researched after Ring Archer Armor, as that technology also gives 1 melee armor to the Skirmishers, while only costing 50 more gold and much less food.

Unfortunately, Tower Shields does not give a true advantage to the Lithuanians in trash wars. The extra pierce armor does not change how much damage their Elite Skirmishers will take from other Elite Skirmishers (even without Tower Shields, their natural pierce armor will already negate an Elite Skirmisher's base damage, while the bonus damage is not affected by pierce armor), while their Halberdiers lack Plate Mail Armor, so they will have 1 less melee armor compared to civilizations that have Plate Mail Armor.

This means that, in a straight-up trash war, the Lithuanian Halberdier will lose in 1v1 against a fully upgraded enemy Halberdier; however, the fully upgradable Lithuanian Skirmishers can reach the front line quicker than other civilisations and try to engage the enemy Halberdiers, while the Lithuanian Halberdiers may focus on enemy buildings, villagers and Hussars.
