Starcraft Protoss Strategy - Beating Marauders  | read this item

There are no doubts that this unit hits hard. The Marauder is the Terran answer to all things armored. That means it will beat up Stalkers, Immortals, and Colossus pretty well. In addition to that, its Concussive Shells upgrade slows down non-massive targets by 50% and when massed will slow down the majority of their opponent’s army. This makes their targets much easier to micro against and even prevent a fleeing foe from getting away. However, it does have its disadvantages.

Marauders cannot attack aerial units. While they may be devastating to armored ground units, they lose their usefulness when their opponent transitions to an air build. You can use this to your advantage to take them out.

Key Units:

Anything that flies and can hit ground units. So, that includes Void Rays, Carriers, and Motherships. Phoenixes do have the capability of taking on Marauders via their unit abilities, but the micro involved in handling them this way makes them a less viable choice.

Zealots with charge are not as affected by the Concussive Shells upgrade and can be quick to get in and start the kill. This maybe an option to use Zealots to cut off a Marauder retreat without getting micro’d down to death.

Immortals, while an armored unit and susceptible to the Marauder’s bonus damage to armored, it does have the Hardened Shields ability. This reduces all incoming damage to 10 as long as the unit has shields remaining. This reduces the potention 26 damage to armored (via full upgrades) down to 10. When the shields drop however, the Immortal will be extremely fragile versus the Marauder.

What other units would you guys use to take out Marauders?
