Form diversified armies. Large groups of tanks are useless against bombers, siege engines soon fall down to hordes of smaller units and fighter jets are of little use against buildings. While forming an army, use various types of units and mix them up, so they back up each other.

Form specialized armies. Do you want to destroy the enemy HQ? Try that with siege engines, use tanks in the form of curtain and back them up with fighter jets. Do you want to destroy multitudes of weak enemy units? Build artillery and tanks to back them up. Do you need to scout the map, before the raid? Airborne and ground scouts, as well as multitude of bombers will get the job done. Do not produce everything that you would like to have. While forming the army, consider what the goals, which it is to achieve, are. Basing on this, create the production queue.

Take higher positions, while fighting. While on hills, your artillery can pound at the enemy with impunity and, without its air support, or taking higher positions, he will not be able to see you. For better defense, take the hill with the artillery and AA units, and block the passage with tanks. Nearby, deploy invisible scouts. Or ones hidden in bushes. Thanks to this, you will be capable of destroying many enemy units, whereas the enemy will be defenseless.

Do not fight near bushes. There is a chance that there is, or will soon be, an enemy inside. This way, he will be able to attack you and leave you defenseless.

Fight from bushes. Turrets attacked by units hidden in thickets, do not respond with fire. The enemy will have to enter the thickets and take heavy beating before he does. Therefore, keep your units in bushes, as often as possible. If you see an approaching enemy and bushes nearby, take cover. This wins you several seconds of unpunished fire.

The only exception are the elite units. They are too big to be concealed in bushes.

Fight on the move. Some of the units can attack on the move. Focus the attention of the enemy units on such units and start to retreat. Sometimes, the opponent rises to the bait and starts chasing you, whereas the rest of your army will be attacking hi, without any repercussions. Another way is to form small groups of units that are capable of attacking in movement and with decent range. Approach the enemy, attack him and retreat immediately. If the enemy's firepower is not strong enough, he will be taking damage without the possibility to respond with counterattack. This tactics is especially effective when you are using several units that back up each other.

Fight from shadows. Units with stealth are mainly weak, but their invisibility makes them perfect hunters. Form a small assault group and send them to the enemy ground. Have them destroy harvesters, hunt artillery down and eliminate airborne targets. Attack, destroy the target and move to a different area quickly. Without the appropriate units, the enemy will not even realize what hit him and where it went afterwards. This type of groups is especially effective against more fragile targets, such as artillery or conduits that conjoin Human buildings, especially if they build oblong HQs that are easy to deactivate.

Concentrate your fire. Focus your attacks on the biggest and the strongest opponents. Wait for them to be destroyed, and issue an order to attack another one. Do not leave this decision for the AI to make, because it will start attacking the closest units. While fighting eight tanks, it is better to destroy two, instead of damaging all eight., because damage does not affect their combat value. A damaged tank is as dangerous as one in full health, which makes scattered fire not worth the time. The exception is the situation, in which the enemy has lots of units protecting a superunit. In such a case, dispatch some of your units to attacking the superunit, and have the rest eliminate the defenders. Destroying Alpha or Hand of Ruk is so time consuming that the defenders deal severe damage, if left alone.

Spare superunits. All of the Epic units have long reload times and the attack takes long. For this reason, they may have problems dealing with big groups of enemies. Simply, they do not have enough time to deal with them all. For this reason, always dispatch them with numerous guards. The guards will deal with smaller targets, whereas the superunit will deal with the more important ones.
