Which tactic would have been most likely to have been found in world war i and not world war ii? a) air combat b) trench warfare c) missile attacks d) machine gun fire

The correct answer is B. Trench warfare would have been found in World War I, but not in World War II.

Explanation:

Trench warfare is a common form of position war in which the fronts consist of a system of trenches. The reason was the technically advancing artillery with more effective grenades and longer gun range as well as the advent of machine guns. At the same time, the mobility of these new weapons was low. The horses that had been used for mobilization until then were just as vulnerable to the increasing effects of weapons as humans.

Such large-scale trench warfare first occurred in 1854 in the Crimean War. Thereafter, trenches were fought, among other things, during the Civil War  and the Russo-Japanese War.

This type of warfare reached a bloody climax in the trench warfare of World War I. In the fighting in front of Verdun alone, more than 700,000 soldiers were killed or injured from February to December 1916, but the course of the front was almost unchanged at the end of the battle. In order to avoid these losses, movable combat command with armored vehicles was developed in Europe and the USA during the interwar period and implemented with the great tank battles at the beginning of World War II.
