Final answer:
Jackie Robinson faced racial discrimination within the US Army, being denied to play on an all-white baseball team and court-martialed for refusing segregated seating
Step-by-step explanation:
Two examples of racial discrimination in the US Army include the treatment of Jackie Robinson and the segregation of blood by the Red Cross based on race. Despite Jackie Robinson's stellar sports background and status as an officer, he faced daily racial slights and was denied the opportunity to play for an all-white Fort Riley baseball team.
His court-martial in Texas for refusing to move to the back of a bus is a prominent instance of racial discrimination. Additionally, the military's practice of segregating "white" and "black" blood during this period, despite medical knowledge to the contrary, exemplifies systemic racial discrimination.
The extreme challenge faced by African American troops, who were subject to second-class status and segregated units, became a prominent feature of military life, contributing to broader societal discrimination and impacting morale and effectiveness.
The experience of black servicemen revealed the profound inconsistencies and prejudices inherent within the military system, reflecting the larger societal discrimination of the time.. Additionally, the Red Cross segregated blood by race during this era, despite scientific knowledge to the contrary.
