Which war marked the first use of chemical agents?

• A. WWI
• B. WWII
• C. Korean War
• D. Vietnam War

Answer: (A)

The first use of chemical agents occurred during World War I, marking a turning point in how battles could be fought. Before this, combat relied on conventional weapons, but in 1915 the German forces deployed chlorine gas at the Second Battle of Ypres, creating a new and terrifying dimension to warfare. This led to rapid development of protective gear like gas masks and new tactics to counter gas attacks, and it prompted further use of other gases such as phosgene and mustard gas later in the war. The other conflicts listed happened after this pivotal moment and did not inaugurate chemical warfare.
