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 +1 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 highest pierce armor in the game, and they even match the Imperial Skirmisher.
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 adds more pierce armor and melee armor than Tower Shields to the Skirmisher, while only costing 50 more gold and much less food.
Combined with the 10% faster movement speed bonus for Spearman-line and Skirmisher-line units, Tower Shields should give Lithuanians an edge in thrash wars.
