Chosen Spearmen

Overall strategy
While these units are burned by very heavy armour, and you will find them very costly to train, you can do no wrong with Chosen Spearmen if you need a powerful, hard-hitting unit suited for defence. This unit has an attack bonus versus unique low-tier Chinese units, namely the Imperial Legate, Han Spearmen, Repeating Crossbowman and Southern Levies, thus making it an important unit when fighting against other players using the Tang as their ingame civ, since its anti-Tang bonus grants it the ability to effective destroy any human wave attacks by them, which will usually be made with armies built up around the use of Han Spearmen.

Yet do take note, that Chosen Spearmen are slow and thus vulnerable to fast ranged units, so always keep units such as Levy Crossbowmen or Scout Cavalry for assistance. Repeating Crossbowmen should be feared especially since they can attack in melee and are also have armour-piercing shot, so make sure that taking them out is a priority if you see your enemies bringing them to bear.
