"Use Jaegers and Templars as your main scouting units.  They're relatively fast, not nearly as fragile as the scout units, and they can quickly retreat over terrain that other units can't cross." - TEM

"When you are configuring your dropships, make sure you put all the necessary battle groups together. (Put weaker units with the stronger units. Or put weaker with weaker, and stronger with stronger.) Like, Main Battle Terradynes with Light Terradynes." - Major BlackHawk

"on level six use your men to guard the turrets and you wont lose as much people." - Edo

"Use the right unit for the job. Also set the unit edition for the job. If it's a defense mission, put a Wolf or Grizzly in defensive and get as many as you can. Or if it's a scouting mission, put scout terradynes in recon mode. Each unit has its place!" - Deacon Stone

"Use the terrain to your advantage, put a small fast unit out in the open as bait, in hold fire mode. As soon as it is fired upon, run behind a small mountain or hill where you have your heavy offensive units. Learn not to expose all of your units at the beginning of a battle, having a troop or two of soldiers in hiding can increase your chances of taking out a group of terradynes. Attack with them once the enemy terradynes are focused on another target, facing the other way." - Just A Guy
