World War II Era Mask

World War 2 has seen an even further improvement in new gas masks design and filter materials, from its previous war. During this time, it was also necessary that the civilian population was informed and trained about possible chemical or biological outbreaks during the war.

As the war had begun, little to no use of chemical and biological weapons happened, unlike World War 1. This is because both sides feared retaliation against their civilian population, with few exceptions among which the use made by the Imperial Japanese Army against the National Revolutionary Army was most notable.

Nonetheless, with increased funding on research, development and production, gas masks were still proven to be important for military forces and civilians, to protect against the threats of chemical and biological warfare.
