"Advanced carryalls can pick up any unit - including the enemy's.  Disrupt your enemy's resource supply by sending carryalls to pick up his/her harvesters and keep them in the air." - TEM

"Make sure to use "infantry rock" (small protected areas on the battlefield) for your troops.  They'll gain an armor bonus and will be safe from vehicles trying to run them over." - TEM

"Place snipers, tanks, and artillery on the ridges around your base for defense.  The height will give them an increased attack range." - TEM

"This is one i thought of myself so i hope it helps if your in a base with one way in put units on the mountains off course and if they attack block your base entrance off right before they get into your base then before more enemy units can come block of the other side so no more can get in then have ornithopters ready for air assault on them then they have no way out of the only entrance they go through all the time" - Ordos Leader
