A panicked, inexperienced soldier will more likely damage his jammed weapon than fix it. Soldiers carrying a flame-thrower can blow up if hit. Soldiers, especially those inside buildings, can become stunned due to the shock effects of high explosive rounds detonated nearby. Experienced tank drivers make the tank more difficult to disable, as they know how to best use terrain and the angle of the tank against an enemy. Soldiers with grenades have a small chance of immobilizing an enemy tank if they can get within a few meters of the tank and place a grenade on the engine or in the tracks.
Prone soldiers are easier to hit if the shooter has a height advantage.
If a soldier goes berserk, he can cause other teammates to go berserk as well. 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.
