General strategies
When you see an ally fighting hand-to-hand with the enemy, help him. Sometimes they will get killed and you could end up alone.
When you finish securing an area, reload your weapon. By doing this you will have a fully loaded weapon in case you are spotted by an enemy.
Ammunition can be difficult to find. It may be a wise decision to assault an enemy with a bayonet or saber rather than shooting them from afar. This tactic can help you avoid tough situations down the road.
Reloading a weapon can be a time-consuming process. It pays to plan your reloading time and engage in hand-to-hand combat when facing a greater enemy force. Keep mobile and be aware of your perimeter when engaging.
One of the most important concepts in warfare, the high ground offers you a better vantage point and firing position.
When you are in a stealth mission, stay out of areas with lights and the enemy cannot see you. Note: If you fire a shot they will be able to spot you.
Never lose a battle
When playing a battle and you are on your last unit, make it move as far as it will go for your first turn and click fast anywhere for your second turn. While they are moving, your first unit moved will get a #1 mark in its area. Click it, and it will move again. Repeat clicking to move to an enemy unit and kill it. Note: If your first unit dies, you cannot use this trick in that battle.
