Welcome to basic training. This won't be exciting, and it won't be fun -- but it's not meant to be. Men's lives ride on every decision you make, and my job is to make sure you are capable of handling that responsibility. If you're the type to get bored and lose your focus we want to know now, not out on the field later. Get some stims before we get started; you'll need them.
The humble trooper is your army's lifeblood. They excel in mountain combat and flanking maneuvers, make great scouts, are reliable guards for your cities, and can shoot down enemy bombers with relative ease. They are the most common of your units, but are still valuable, so do not throw their lives away.
Your tanks are the backbone of your army, your heavy armor. They roll over enemy troopers and are ideal for sweeping for enemy scouts. They are devastatingly effective at stopping enemy armor when flanking. Their size and weight costs them dearly in mountains and makes them a clear target when assaulted by bombers, so be careful with your orders.
Bombers are your cavalry, packing both mobility and strength into one expensive unit. They can move twice as far as any other unit in your army, but will run out of fuel if they aren't inside or next to an allied city after moving. Bombers are highly effective against tanks but must be especially wary of troopers in mountains -- a single trooper dug into mountainous terrain can shoot down a bomber flying overhead.
Your troops are in the field, but you can directly support them with special operations. There are three types of ops available for you: satellites, missiles, and drop pods. Satellites are the most frequently ready and reveal the target territory, missiles are received half as often and destroy every combatant in the target territory, and drop pods are provided with every third satellite and place four troopers and two tanks in the target territory.
Knowing the ground your troops must deal with is mandatory if you're going to make good decisions. Plains, cities, and mega cities are all open combat zones where tanks are at their most effective and sight is unobstructed. Mountains are much harder to navigate, and obstruct sight so that your units can't be seen by nearby enemies. Your troopers are mobile enough to take advantage of this and will fight more effectively in mountainous terrain. The last significant territory type is lakes, which block your ground based units from moving through them.
Cities that your units are defending will produce a steady stream of recruits and equipment to reinforce your army. Your logistics officers will organize the distribution network so that the cities in the center of your control receive more production than the outer cities. This improves efficiency of both manufacturing and troop deployment. This production is lost in cities where your troops were engaged in combat -- the supplies will arrive but nobody will be paying attention, and loose resources during war tend to disappear.
Still keeping up? I'm impressed, most of our recruits have their eyes glaze over before they learn what an op is. Remember this: at the end of these lessons there will be no test except the lives of your men. It's time to pass you off to your next instructor for instructions on the technical side of running this war.
