What are your favorite units in the game?

Artillery- An on-map Bm-27 Uragan batallion is 250 points, half the price of a comparable MLRS unit. The cluster munitions are good against ANYTHING and if you buy an ammo dump you can keep pouring fire for almost the whole game. If you can't buy that, at least get some small cheap mortars for suppression and smoke fires. Mortars are excellent because they have a lot of firepower for their price.

Tank- Russian Chiormy Oriol. Slightly cheaper than an Abrams, and it's the only Russian tank with a fire control of 50 (enough to see through smoke). You have to buy it in the Export Tanks section under armor, to anyone having trouble finding it. It has less armor than an Abrams, but is still decent. The main reason I like it is not because of fighting ability, but just because I think it's cool that Russia has finally turned out a tank truly equal to Western models.

Infantry- FN MAG machine guns. Any machine gun works very well in open terrain, but the western ones tend to be more lethal. In close terrain, machine guns are usually less effective than assault rifle infantry, though, because numbers matter more in that situation. USMC infantry are the best because of high morale and experience and good weapons.

Air- Against an enemy witout air defences, helicopters are excellent. Any helicopter will do, as long as it has modern ATGMs. In pre-1980s scenarios, though, helicopters have poor anti-tank capability, and you should only buy a few cheap ones for scouting.

In terms of airplanes, the American B-2 is the best. It costs 999 points, but carries SIXTEEN standoff JDAMs. You could destroy the whole enemy army without them firing back, because it has a high enough EW rating to aviod most area SAMs.

Air Defence- Stinger SAMs or ZSU-23-4s. Stingers are cheap and the most accurate MANPAD avaible. I don't usually buy area SAMs because they're pretty inaccurate considering their cost and are vulnerable to anti-radar, but they're useful if the enemy has stand-off bombers.
If you don't like MANPADs for some reason or want a good anti-infantry weapon to double as air defence, buy a ZSU-23-4. They're not too accurate, but are cheap enough to pay for themselves if they kill a few enemy.

APC- BRDMs, or anything with just enough armor to repel bullets. I don't generally use APCs because they're too lighly armed and armored to survive on the battlefield anyway- that's a tanks job. It's best to buy something with just enough armor to survive small-arms fire, because anything else is a waste of money.

ATGM- Javelin. With a range of over 2,000 meters, top attack capability and very good accuracy, it's by far the best. All you have to do is make sure that you prevent them from being surpressed by artillery.

Recon- If you can't buy a recon drone, buy a helo. If you can't do that, buy something heavy enough to shrug off almost anything that the enemy will throw at it (if you recon survives he'll get a better picture of the enemy). If you can't find anything with that kind of armor, get a jeep or Humvee. Infantry have good spotting, so load them into your recon vehicle and dismount them when you contact the enemy. If the vehicle dies, at least you'll have a hard-to-spot infantry recon outpost.
