During World War II, promotion rates in the U. S. Air Corps were so rapid for the group as a whole that many individual soldiers in this military branch were unhappy about the speed at which they were promoted. Their unhappiness is best explained in terms of:

Relative deprivation principle.

Explanation:

World war II was a war that started on the 1st day of the month of September, in the year 1939 and it ended on the 2nd day of September, in the year 1945.

During the world war II the military branch were not happy because the rate at which the U.S. Air Corps were been promoted is higher than them. So, Sociologists and Psychologist used a theory to explain the attitude of the military branch and the theory is known as the RELATIVE DEPRIVATION PRINCIPLE.
