Under which circumstances can military operations be categorized as major operations and campaigns?

Military operations can be categorized as major operations and campaigns specifically when they are deemed necessary during crisis response and limited contingency operations. This classification reflects the scale, complexity, and significance of the operations involved, which typically require extensive resources, coordination, and planning. Major operations and campaigns are defined by their goal of achieving significant military objectives and often involve large units or formations, extensive logistics, and the integration of various military capabilities.

Crisis response and limited contingency operations typically arise from unforeseen circumstances requiring immediate action, making them critical scenarios where superior military strategy and execution can facilitate stability and peace. These operations often necessitate decisive and scalable military efforts that align with national objectives, thereby elevating their importance within the military framework.

While humanitarian assistance efforts, military engagement, security cooperation, and peacekeeping missions have their own roles and significance within military operations, they do not inherently carry the same level of complexity and resource commitment associated with major operations and campaigns. Major operations are more directly focused on achieving defined military objectives in response to threats or crises rather than broader, often less immediate missions like those described in the other choices.
