-When given the chance, pick up a Kak 98. 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 2 bunker in the building.
-The most common bolt-action rifle is among the best guns for small groups of enemies. It may be a bolt-action, but it is a one-hit kill almost all the time. Make sure to keep an automatic for the slow reload.
-Smoke grenades provide instant concealment and thus are very useful for getting close to tanks on the Russian front.
-SMGs are better at close range. The PPSH 42 is recommended.
-Rifles are useful at short to medium range, the best ones being the SVT40 and Gheher because they are semiautomatic.
-Sniper rifles are very useful for taking out machine gunners before they can get set up. The Gheher sniper rifle is recommended because it is semiautomatic.
