Enlisted Expeditionary Warfare Specialist (EXW) Practice Test

The option that is not an NECC command is indeed the Naval Expeditionary Force (NEF). The NEF is a broader operational construct that integrates and coordinates various expeditionary capabilities and forces across different commands, but it is not a specific command under the Navy Expeditionary Combat Command (NECC).

In contrast, the Naval Construction Force (NCF), the Naval Expeditionary Intelligence Command (NEIC), and the Naval Expeditionary Logistics Support Group (NAVELSG) are all established commands that fall under the NECC. The NCF, often known as the Seabees, is responsible for construction and engineering tasks. NEIC focuses on intelligence operations supporting expeditionary forces, while NAVELSG provides logistical support for expeditionary operations. Each of these plays a vital role in the Navy's expeditionary warfare capabilities, further emphasizing why NEF, being a collective operational force rather than a command, does not fit in this context.
