Bronze age technology
Explanation:
The people of Mesopotamian developed many technologies, some of them were metalworking, glass making, textile weaving, food control(agriculture), and water storage and irrigation. They were one of the first Bronze age people in the world, they used copper, bronze and gold, and later they used iron.
Of what is listed Germany lost the highest percentage of its population. Their numbers, though, were no where near the percentages of what was lost by the USSR. More men were lost there. Russia actually had both men, women, and children fighting in the war. This allowed for a greater chance of more loss of life.
