What is the location of a Level 3 facility?

The correct answer identifies Fort Leavenworth, KS, as a Level 3 facility due to its designated role within the military training and operational framework. Level 3 facilities typically focus on advanced training, strategic operations, and support for various military branches, including the Navy. Fort Leavenworth is known for its comprehensive military training programs, particularly in leadership and strategic warfare, thus making it fitting for this classification.

In contrast, locations like Norfolk, VA; Charleston, SC; and San Diego, CA, serve other important roles but are not categorized as Level 3 facilities in the context of this question. Norfolk is primarily known as a major naval base, Charleston serves more as a logistical hub, and San Diego is recognized for its significant fleet concentration and naval operations. Each of these facilities has its own unique contributions to the Navy and military readiness, but they do not align with the specific characteristics that define a Level 3 facility as exemplified by Fort Leavenworth.
