*Light units are generaly better (more gain/less cost) at unit vs unit combat than heavy ones.
*Heavy units are generaly better at attacking the enemy defenses than light ones.
*Radar jamming can be used in various ways, so use it and dont forget your enemy may be using it too.
*Always expand. Even if there is no economic value into expansion, it at least
pushes the front line in the direction of the enemy base.
*Use the height to your advantage. Defenses built in the top of mountains will give your enemy a pretty hard time.
*Never forget to make AA! even if the enemy aparears to have no air, remember that he may be hiding it for a surprise (and probaly devastating) attack!
*Keep in mind that nukes are pretty easy to block, so ideally you should try to destroy your enemy in some other way.
*A undefended wall will never hold anyone for long, so dont think your enemy will not manage to invade your beach just because you made a dt wall.
*Reclaim wreckage. Many people forget this or think its pointless, but a unit wreckage haves around 50% of the unit's original metal and reclaiming it is very fast.
*Dont born in the same place as one ally just because you like that spot. He got here first, you gotta respect it.
