Advance Wars: Dual Strike/Strategy

Now that we've covered the basics of the game, we'll learn about playing effectively. First some units of notice, then some good rules to know.

Units of Significance
These units are units that have a large part in the game such as, battle copters, mechs, and so forth. See also Advance Wars: Dual Strike/Units

Battle Copter Battle copters are one of the games most rounded units. They are cheap at 9,000, only 2,000 above a tank, packs the same amount of firepower but takes less or no damage from many units. They work extremely well in the beginning of the game to weaken infantry to stunt the enemy's economic growth and to pick off vehicles. However, any anti-air type unit will make mince meat of it so it will become toast once fighters and carriers get out.

Stealth Fighters Stealth fighters are a mix between a fighter and a bomber. It can do both of the jobs but doesn't do them as well. However, it gets a very important bonus, the ability to cloak itself. When cloaked, it becomes unhittable by all units with the exception of fighters and stealth fighters. It's a unit that's most usable at the end of the game because of it's price, 24,000. To use it very effectively, build 3-5 of them and cloak them all. Sneak them up to the enemy and strike the indirect units in the back, then use them against the tanks when your army comes through. Remember that APCs can refuel any unit they are adjacent too which can save a couple of turns trip back to the airport when a stealth inevitably runs out fuel.

Neotank Neotanks are generally the best of the tank series. They have a movement of six, better than the medium tank. The machine gun is powerful enough to kill most infantry in one hit and the cannon is perfectly able to fight against other neotanks, medium tanks, and normal tanks. The only thing that can stand up to it in direct combat is another neotank and a megatank.

Mech The mech is a version of the infantry, it has a slightly stronger machine gun and a bazooka. The bazooka is as powerful as then tank cannon. With it's bazooka, it's made into a fine choice for capturing bases in a contested area early in the game. It still captures bases and destroys light vehicles.

Anti-air Rips through helicopters and suprisingly effective against mech and infantry. Vulnerable to other units however.

Bomber Can't be touched by most ground units and packs a real punch.

Repair
When you repair, you pay one tenth of the unit's price for each hitpoint. Right now you might be thinking,

"One tenth the price for one HP? That's a ripoff! I could have a brand new unit for twice the price and do it in one turn AND have a weakened unit!"

Hear me out though, repairing is worth it. We'll put it this way. A unit at full hitpoints is worth more two times the cost of a unit that's half destroyed. The hurt unit will deal less damage when striking first, take more when striking first, and does less damage if any in a counter attack. The reason a full unit is worth more than twice the cost of the hurt one is because it will take less damage when attacking first.

If you have a unit at five hitpoints and a base, the logical thing to do is to repair unless you need the base. If you spend the money to make another one of that unit at full hitpoints, you will have for the full price of one, one good unit and one pretty much worthless unit. If you repair, in three days for the price of half of the unit, one good unit. Now about repairing technically, at a base that can repair it, you will restore 2 hitpoints a day with the exception of Rachel who repairs 3 a day.

How-To
Thise section will show how to do common tasks in advance wars such as to take control of an enemy HQ or how to decimate a large battle field. Remember that these parts are general and may not work depending on the conditions.

Control a Battlefield
This advice is generally for smaller maps where there are multiple people wresting for control. It creates the low funds and necesity to control a central area with many bases. If it is like this, there will probably be a few people that have captured a base and are fighting there. Everyone will be churning out weak units as fast as they can in efforts to stop opponents from capturing bases. The big secret is to build a giant powerful tank such as a megatank that can blow away most of the units in one hit. Support it with two or three medium tanks, and capture the bases with mechs. If you have enough bases, build a lot of mechs to fight the light vehicles. This tactic works very well with Jess and Max.

Control a Bridge
Bridges are essential to winning the game. Having control of one will block all of the enemy units from coming through, but you need to know how to control one. The big parts to a bridge block are a fodder such as APC's or heavy tanks to block the enemy from going through, and a few indirects such as rockets and battleships. Place the fodder in the passage, and place the indirects behind it. With this, as long as you can keep a fodder in the way, you should be able to control it. However, it's a different story if you want to take one from your enemy. To do that, you should use air units or indirects to take out the indirects, and destroy the fodder with your tanks and indirects. If you can't destroy the indirect, you should build a few neotanks and maybe a megatank depending on how strong the fodder is. Place them right out of range of the indirect, and when you use a CO power, move them in and try to OHKO each one to make room for the next. After that, defend your bridge!

Blockade
If you can create more units than your enemy you will clearly have an advantage. Leaving a low value or nearly destroyed unit on any enemy's base stops her from creating new units at little cost to you. This strategy can be very effective if: Even if you can't occupy the base for long, forcing your enemy to miss a couple of rounds of production may give you a game winning numerical advantage.
 * you can occupy all of her bases
 * there are no other enemy bases or units nearby
 * you want to hold the base until you can bring infantry up to capture it

If the direct blockade is not possible it may be useful to blockade a base or port by trapping an enemy unit on it. Direct combat units can't move after they fire so surrounding a newly created tank with cannon fodder on 4 sides means it can only escape with external help or during a double move dual strike. Of course you have to have a supply of cannon fodder available to replace the one it targets each turn but with a base nearby this may be a cheap method of dealing with a mega tank.

The AI will sometimes use this strategy if you create a battleship. Ports usually have only a single adjacent sea square. A lander or other cheap boat on this square is too close for the battleship to hit leaving you unable to leave port and unable to create any other boats without deleting your expensive battleship. Avoid being trapped by creating a suitable direct combat unit and moving that to the adjacent sea square first.

Cannon fodder
If you've no interest in (or hope of!) destroying attacking units but need to contain them then deploy some cannon fodder to surround your indirect units, bases or just to slow an enemy down at a choke point. The idea is that she has to use a turn to destroy them buying you time to do more indirect attacks, create the right attacking units etc. Infantry and recon are ideal as they are so cheap but you can also use almost destroyed units or anything you no longer have a use for eg anti-air missles once all enemy air is destroyed. Remember, no matter how tempting, don't attack the enemy as this gives them chance to retaliate. The aim is to hold up the enemy, not damage it. Of course if she has superior numbers then you'll need lots of cannon fodder units to succeed with this strategy.
