Allies
The Allies is the side which has the potential largest and strongest economy; that is obtained through their comparable low maintenance fee for their structures and the industrial plant which decreases the cost of all units and structures. Furthermore, the Allied units are not as expensive to start out with as those of Germany nor Russia, however, they don't pack the same punch as the weapons of the two other sides.

On the battlefield the Allies rely on their high mobility and air force, what the allied vehicles lack in armour the air force makes up for in firepower - the Allied Typhoon is the most efficient tank buster in the game. The allies also have the ability to use their spy plane (P-38) which gives them an edge against the Germans and Russians who have to scout with conventional means; often resulting in an expensive campaign to simply gain enough battlefield information to wage an efficient campaign against their enemy.

Germans
The Germans are without an doubt the most versatile of the three sides, they have many types of strong infantry and vehicles available to them. The high maintenance fee of the structures combined with the high cost of their units do, however, result in the necessity of well-thought plans of attack as Germany is the side which has the hardest time re-building up its forces. A failed attack can easily result in Germany losing ground and "Capture able oil derricks" which is a catastrophic blow to German economy and can essentially lead to defeat. Germany is, though, the side which can build up an early army the fastest, due to higher build rate of production sites, which means that Germany is the best fit for an early rush of the enemy.

The Germans are a force to be reckoned with on the battlefield, their units are among the strongest in the game and that goes for both infantry, tanks and fighter planes. Their low number is made up for by quality, a small German force can break through well defended Allied and Russian positions - Germany does, however, rely of efficient combinations of their units, the German dive bomber (Stuka) is the unit which fit the best into a support role of all air units as it is the only multi-purpose fighter plane in the game. While the German infantry is good, it has to be backed up by other unit types, such as tanks, since it is a hard blow for any German commander to lose large groups of units - combined they can often overcome much larger forces.

Russians
The Russians use the exact opposite approach on the battlefield than that of Germany. Russia pulls from large amounts of units of questionable efficiency at best, the infantry is cheap and tanks are fast to produce which creates a horde effect. Russia is the side in the game which can build the most oil derricks, this means that once the Russian economy is fully build it does no have to rely on capture able oil derricks such as the Germans, and the Russians can therefore simply "starve the enemy to death" through a war of attrition by destroying everything on the map and build up its own forces.

The Russians rely on constant pressure on the enemy to win, since everything they poses is either fast to build or very cheap, units can be pumped out of the factories at a pace second to none. The early Russian artillery (Katiusha) is an important part of any Russian commander's force, since while being weakly armoured it is also the most versatile artillery unit in the game, capable of supporting an advancing army with coverage fire or simply bombard an enemy position or base.
