In Veteran mode, your life expectancy is cut to three or four shots until you die. However, Veteran mode does not improve the enemy's aim or strategy. Use small blocks or small bulges of hills as cover and crawl, because you do not get points for kills, so do not take the Nazis head on. Let your allies lay some fire, if there are any. If not, throw a smoke grenade and shift between crouch and crawl positions, laying cover fire and stall some time for the smoke grenade to spread before the Nazis rush in. Use this smoke cover to fall back to the nearest safe position where you can regroup or hide and pick the Nazis off from afar.
Even after you shoot the enemy, he may still be alive. Make sure to aim your crosshairs at him and see if it turns red. If it does, it indicates that the enemy is still alive, and you must shoot him again. Do not give the enemy the chance to shoot you from behind while he regains consciousness.
The grenade indicator is useful, however, you do not have to run away from it every time. If the indicator points that a grenade has landed near you, but you are taking cover behind a wall, you do not need to run away. Instead, the grenade will explode and not damage you at all.
Head shots are instant kills. Body shots require two or more shots for a kill.
When you find a Kak 98, pick it up. It is one of the most powerful guns in the game. There is a scoped-Kak 98 in the last level (Dragon's Teeth) in the second bunker in the building.
