The classic WW2 knife used by the Green Beret
The knife is a weapon and tool used by the Green Beret and the Marine.
In Commandos:Behind Enemy Lines its the most silent way to kill an enemy soldier.
However in Commandos 2:Men of Courage the Diver can throw the knife to kill an enemy soldier from a distance, whereas the classic stabbing ability is still kept for the Green Beret.
While killing enemy soldiers with the knife the player must be careful where he does it because the enemy can hear the killing take place. Another very important thing to remember, while using a knife with the Marine is to pick it up after thrown.
In Commandos: Strike Force the Green Beret and the Sniper carry a knife (in which the Sniper takes the Diver's throwing ability), though the Strike Force's Green Beret mostly uses it as a fall-back in Combat, in Strike Force, the Green Beret's Knife is based on a KA-BAR Knife while the Sniper's Throwing Knives are based on the Fairbairn–Sykes fighting knife.
