Mosin-Nagant

The Mosin-Nagant was the standard issue Soviet rifle during World War II. It was chambered in 7.62x54mmR and had a five round internal magazine loaded by stripper clips. It is seen in all Call of Duty games featuring Soviet troops.

A scoped version available in some situations. Due to the placement of the scope, it is impossible to reload a scoped Mosin-Nagant with a stripper clip in real life, but its reload animation Call of Duty and Call of Duty: United Offensive show a stripper clip being used anyway. In reality, each round would have to be loaded individually. It isn't until Call of Duty: Finest Hour that you load the rounds individually in the chamber.

Call of Duty 1 and United Offense
The Mosin is your average bolt-action rifle, and it has a five round magazine. What separates it from the others is it's extremely small and accurate ironsights. Basically, if an enemy is inside them and you fire, you'll hit them right where the circle was. This weapon will kill an enemy in one shot if you fire at the chest or head. That combined with the extremly-accurate ironsights makes this a very, very deadly weapon.

The Mosin has a sniper variant. To hit an enemy, make sure the area you want to hit is on top of the pointed line. Unlike the other sniper rifles, the Mosin is reloaded with one clip, making it much easier to reload than the others.

Call of Duty 2
The CoD2 Mosin has been nerfed, compared with it's CoD1 counterpart. It's ironsights are much larger and it's sniper variant must be reloaded one round at a time. Otherwise, it's the same.
