The First Infantry Regiment of the New Mexico National Guard was mobilized how soon after the U.S. entered the war?

The First Infantry Regiment of the New Mexico National Guard was mobilized very soon after the U.S. entered World War I in April 1917. Within weeks of the declaration of war, the regiment was called into federal service, reflecting the urgency of military needs during that time. This prompt mobilization was part of a larger national effort as the U.S. sought to quickly build its military presence in response to global conflicts. The immediate activation of state militia units like the New Mexico National Guard highlights the commitment of local forces to national defense at the onset of the war, contributing to the overall readiness and operational capabilities of the U.S. Army.
