Cataphract is the armored front runners among all troops. Its default behavior is to seek and destroy defenses. After all the defences are gone it will behave like a heavy infantry troop. With a large amount of hitpoints, it can endure more than any other troop of its age, as well as dealing a lot of damage before falling. However, its disadvantages are that it has low damage and can be killed easily by Ballista Towers, Cannon Towers or Anti-Tank Guns.
A Cataphract was a form of armored heavy cavalry used in ancient warfare by a number of peoples in Europe, Asia and North Africa. Historically, the Cataphract was a very heavily armored horseman, with both the rider and mount steed draped from head to toe in scale armor, while typically wielding a kontos or lance as their weapon.
Cataphract has a lot of health but is slow and has low attack power, so use it in groups.
Cataphract is weak against many defenses grouped together.
When pushing for trophies, you would need to destroy the Town Center or City Center. In many bases, the town center would be in the center of the base. First, train up an army of Cataphract and a Wall Breacher. When attacking, deploy your Wall Breacher and wait till it destroys the necessary walls. Then, deploy all your Cataphract units in the areas which the City Center is more close to. If there are a few defenses blocking the way, destroy them. Then rally your units to destroy the Town Center or City Center.
Cataphract would ignore defensive troops and would pursue their targets which are defensive buildings. However, if a defensive troop attacks it, the Cataphract will attack back until the defensive troop is killed; thus making it distracted. Try to use and deploy Ranged Infantry or Heavy Infantry after deploying the units to eliminate the defensive troops.
