In which type of operation would you likely focus on operating covertly while remaining undetected?

The focus on operating covertly while remaining undetected is best represented by infiltration operations. Infiltration involves moving forces into enemy territory without detection to achieve specific objectives, such as gathering intelligence, executing sabotage, or preparing for a larger engagement. This type of operation relies on the element of surprise and stealth, requiring troops to move discreetly and often under the cover of darkness or through natural terrain that provides concealment.

In contrast, frontal attacks, flank attacks, and turning movements generally involve some level of exposure and engagement with the enemy, where the objective is to confront and overwhelm the opponent. In these cases, the goal is less about remaining unseen and more about achieving a tactical advantage through direct combat maneuvers. Therefore, infiltration stands out as the operation type distinctly emphasizing covert actions and remaining undetected.
