A soldier under fire has a much harder time hitting anything when he returns fire. Soldiers carrying heavy weapons such as machine guns get fatigued more quickly and run slower. Soldiers in depressions such as foxholes and trenches cannot be overrun by a tank, and more experienced soldiers will actually try to move out of the way first. Teams by themselves and without a leader are adversely affected if they are ever outnumbered, and are likely to flee if shot at by the enemy. Teams undergo stress if they are outnumbered, surrounded, fired at by a tank, caught in the open, or ambushed.
Teams get a morale boost if they outnumber, ambush, or kill the enemy.
Moving a Commander near soldiers that are panicked will help rally them. Experienced teams will employ advanced squad tactics when moving. For example, in some settings one or more soldiers ahead of the rest of the team will stop to provide cover from the enemy while the rest of the team runs by. Friendly fire can and does occur, especially if machine guns are involved or if high explosives are used. Shooting explosives or fuel barrels on the map will cause them to blow up, possibly causing a chain reaction.
