If you look at the statistics of World War II, then less than 1% of injuries sustained by soldiers of the Soviet Army, were from the cold weapons, including more than half of careless handling of weapons by the soldiers themselves. Others soldiers - from bullets and bomb explosion.
Last summer, in the battle for the hill Saur-Grave of the Donbass (strategic hight ground. About 200 km. from my home) was the largest melee battle. Rebels defending Saur-Grave, fighting with small infantry shovels. Ukrainian army could not seize the high ground.
All other big battles of this conflict have won those who have the advantage in tanks and artillery (Debaltsevo Ilovaysk, Izvarino).
Knives Glock little help to the army of Ukraine.
Rebels are using any knives. I have many friends among the rebels.
Small infantry shovels are very popular in Russia, they often carry in the car, as in America baseball bats.
On the Russian forums in polls about the knife on the war often wins here this pair.
Sorry for my English. I got used to three times of a verb, and their fourteen. Or sixteen? It is impossible to understand why?
