In depth character development. Players design their character and then build them up over time. Here are a few archetypes that players might consider:

Medics - Everybody loves a doctor. Medics gain experience by healing people and are a vital component to every squad.

Mechanics - You break it this guy can fix it. From broken tanks to armor that needs a patch mechanics are kept busy behind the lines.

Demolitions - A specialist in all things that go boom. A demolition’s expert can even up a situation by blasting down the heavy defenses with perfect timing. Given the dangers of handling explosives unskilled or careless demolition’s men are known as “pink pancakes”.

Drivers - Not everybody can jump into a tank and drive it around, you need a driver. A good driver can equalize the battle by throwing his 30-ton tank around like an ice skater.

Heavy Weapons Soldiers - You want that ion cannon to fire in the right direction? You better have one of these grunts backing you up.

Commanders - Certain bits of equipment can only be used by characters with the leadership skill. These include the combat coordination systems which allow leaders to track all of his teammates on a modified radar screen and direct them by use of waypoints that he can place. He can also “laser designate” areas for long range bombardment.

Spies - Specializing in stealth this character uses lockpicks, camo- suits and uses silent weapons wherever possible to prevent giving away his position.

Psionics - Distrusted by many because of their trait of running away when the combat gets near, psionics never the less have access to incredibly powerful powers. Psionics often shun squads of non-psionics or ‘deads' as they call them and form their own squads known as “coteries”.

Infantry - Trained in good old-fashioned man-to-man combat, it is hard to overestimate the power of a highly trained infantryman. At the end of the day you need a good number of infantry if you are going to take and hold territory.

Of course the above are just suggestions. A look at the character generation screen will reveal that players in fact can pick and choose various strengths and weaknesses on their own tastes.
