Your team can commandeer any vehicles they come across in the field, too. These range from snow buggies on the Russian levels to school buses and military vehicles like jeeps and tanks (hooray!). The tank's weapons can be employed to cause yet more havoc, and although running over as many guards as possible isn't often a practical way of achieving objectives, it is great fun nevertheless. Sniping enemy troops is a very powerful way of making progress later in the game - it is possible to take out a guard long before he knows you are there, and it is a good thing this weapon is restricted by the limited availability of ammunition. It means your sniper is one of the most important team members - protecting him (or, as it usually is, her) is vital.
