Why should soldiers be discouraged from adopting stray or injured animals as mascots?

The correct answer highlights a significant health concern associated with adopting stray or injured animals as mascots. Stray animals can carry various diseases that pose risks not only to the individual who adopts them but also to the larger group, particularly in military settings where maintaining health and readiness is crucial.

Examples of diseases that can be transmitted include rabies, leptospirosis, and various parasitic infections. The close quarters in which soldiers often live and work can facilitate the spread of these diseases among the group, leading to potential outbreaks that could hinder operational effectiveness.

While the other options may present valid considerations, they do not encompass the primary health risks and complications that arise from the potential disease transmission. The focus on health safety in military environments makes it imperative to maintain a disease-free status, thereby underscoring the importance of discouraging the adoption of such animals.
