What is the term for anything used to disguise oneself, equipment, or position to avoid detection?

The term "camouflage" specifically refers to techniques and materials used to blend in with the surrounding environment to avoid detection by enemies. This can encompass various methods, including the use of coloration, patterns, and strategic placement of equipment or personnel to make them less visible. Camouflage is employed extensively in military operations to enhance stealth and reduce the likelihood of being spotted, thereby protecting both individuals and critical equipment.

In contrast, while "concealment" also involves hiding something from view, it does not necessarily incorporate the aspect of blending in with the environment, which is fundamental to camouflage. "Cover" often refers to physical barriers that protect individuals or equipment from enemy observation or fire but does not focus on the visual aspect. "Disguise" refers to altering appearance to mislead or fool an observer, which may not be specifically aimed at avoiding detection in a military context like camouflage. Therefore, the specific focus of the term on blending in makes "camouflage" the most accurate choice.
