Sniper
In World War II, snipers were common. They were an important part of the fighting. Every squad of the Soviet army included sniper or a 'marksman'. Camouflage tactics were developed during this time. Snipers were very useful during the Battle of Stalingrad. One Russian sniper was said to have killed over 240 German troops. Even that wasn't the best. Mihail Surkov killed 702 enemy troops and Semen Nomokonov killed 367 by sniping, including a general.
