Applicable to Two or More Groups:

• Garrison your infantry in civilian buildings instead of building new structures. It’s best to have a mix of troops in there, as some are better than others against certain enemy units.
• The GLA’s Toxin Tractor and the Chinese Dragon Tank can destroy a building in a single shot, so make sure you evacuate a garrisoned building if you see one of those units headed toward it.
• Keep your supply centers as close as possible to your supply piles, so that the gatherers don’t have to move as far to drop off their loads.
• Take the high ground whenever possible. You can fire down on the enemy before they can get up where you are.
• Keep that old kids’ game “Rock, Paper, Scissors” in mind when assembling your forces, especially if you know what your enemy is building. Every unit in the game has a weakness, so exploit it: send vehicles equipped with anti-aircraft missiles against planes and helicopters, for example. (You’d be surprised how many gamers don’t consider this and just amass a huge army of whatever units they feel like building.)
• Use rally points to make sure that your newly created troops and vehicles aren’t just standing around your base. Move them out to a position where they can do some good, especially if you’re otherwise occupied and don’t have time to go back to your base and manually direct them.
• Patrols are another good way to make sure your newly created units have something to do while you’re mounting an attack. Set up patrols along the perimeter of your base.
• Move land vehicles and ground forces ahead of artillery, allowing you to simultaneously hit the enemy head-on with the front line and from above with the artillery.
• Create unit shortcuts by dragging a box around a group of them and pressing the Control key and then a number. Now every time you press that number, you’ll immediately begin to control that group. You can do the same thing with positions on the map, but press one of the F keys to create those shortcuts.
• In addition, the H key allows you to quickly jump to your Command Center, and pressing the Spacebar any time you’re alerted to an attack on your forces brings you to the scene of the skirmish.
• Vehicles only have to bump infantry to instantly run them over and kill them, so use that tactic rather than staying back and firing at them. This is highly effective against troops armed with missiles, as they can make fast work of a slow-firing tank.
• Flanking moves are an effective way to take out an opponent who has built her defenses in anticipation of a head-on attack. Fire away from both sides and you’ll likely take out her defenses before she can decide where to shoot.
• Sometimes it makes sense to amass an army as fast as possible and rush a nearby enemy, taking him out or doing severe damage to his forces before he can mount a defense. Use spy units to check him out his strength first, if possible.

Fight Fire With Fire. Few units can run into a trio of Dragon Tanks and survive.

Weapon of Mass Attrition. Certain weapons’ residual can continue to damage nearby units even after deployment.
