Read the following passage:
During the First World War, military medical officers struggled with waterborne pathogens that compromised combat readiness in frontline trenches. Field water purification initially depended on boiling, but this method consumed scarce fuel and produced smoke that exposed troop encampments to enemy reconnaissance and artillery. To mitigate these operational liabilities, units deployed mobile chlorination apparatuses using calcium hypochlorite. Although soldiers frequently complained of the harsh taste, chemical treatment eliminated enteric disease outbreaks without producing visible emissions. By examining this technological transition, the author demonstrates that combat medical advancements are often shaped as much by tactical concealment and resource scarcity as by germ theory.
Based on the passage, the author discusses the smoke produced by boiling water primarily to illustrate how tactical concealment requirements compelled military planners to adopt chemical purification methods.
