What was a key reason for the formation of the Alaska Territorial Guard?

The formation of the Alaska Territorial Guard was primarily driven by the need for defense during World War II. As the Japanese forces threatened the Pacific coast, the U.S. Army recognized the importance of having a local force in Alaska that could respond quickly to any potential military incursions. The Alaska Territorial Guard was established in 1942, comprising mainly of local Alaska Natives and residents who were familiar with the harsh conditions and geography of the region. This local knowledge was vital for reconnaissance, defense, and support roles, especially in the remote and challenging terrain of Alaska.

The other options do not accurately reflect the primary motivation behind the Guard's creation. Promoting tourism or enhancing economic development were not immediate priorities during a time of war, and while assisting local law enforcement can be a function of a national guard, it was not the critical reason for the establishment of the Alaska Territorial Guard in that historical context. The urgency and necessity of military preparedness to defend the territory from invasion were at the forefront of the Guard's formation.
