Final answer:
Concealment in military terms, as referenced in Marine Corps Warfighting Publications, is the act of hiding from observation or surveillance without necessarily providing protection against weapons.
Step-by-step explanation:
In military terminology, particularly within Marine Corps publications such as MCWP (Marine Corps Warfighting Publication), concealment refers to protection from observation or surveillance. Concealment does not necessarily stop projectiles, lasers, or other weapons; it simply hides the person or object from view. For instance, soldiers may use vegetation, terrain, smoke, or other elements of the environment to make themselves less visible to the enemy. It's a critical tactic on battlefields to gain strategic advantages and to mitigate the risk of being targeted by enemy forces. Concealment plays a crucial role in military strategy and is a fundamental concept taught to military personnel.
