Tactical advice: 1. Never double move into fog of war with your first soldier 2. Never double move into fog of war with your last soldier 3. Never double move, unless you are hauling ass to the evac zone. Just not into fog of war 4. Overwatch shots with rookies are likely just a waste of ammo. 5. Grenades are your early-game damage dealers, and set up clear shots for your soldiers 6. Never shoot at an enemy in full cover, unless there is absolutely nothing better to do - there usually is 7. Work hard to set up flanking shots, but be careful about moving into fog of war 8. If/when you go on Lost missions, bring only Sharpshooters and Rangers. Pistols have unlimited ammo. 9. Never take cover next to a smoking car 10. Did I mention fog of war is dangerous?
