What is the least active defense capability for a convoy movement type?

Infiltration is considered the least active defense capability for a convoy movement type because it focuses on stealth and evasion rather than direct confrontation or strong defensive measures. This tactic typically involves moving through enemy territory in a discreet manner to avoid detection and does not emphasize the defense mechanisms that are crucial during an overt convoy operation.

In contrast, other options like Combat Logistics, Standard Convoy, and Quick Reaction all imply a more proactive approach to defense. Combat Logistics entails preparing and supporting combat operations, ensuring that the convoy is well-supplied and guarded. A Standard Convoy generally involves implementing security measures and formations designed to protect the movement actively. Quick Reaction is related to having the ability to respond rapidly to threats, emphasizing immediate defensive postures, making these options more suitable for active defense capabilities. Therefore, infiltration does not provide the level of active defense required for a convoy, thereby categorizing it as the least active among the given options.
