How many ranger companies were formed during the Vietnam War and how many actually went to Vietnam?

During the Vietnam War, a total of 15 Ranger Companies were officially formed as part of the U.S. Army's commitment to utilizing specialized light infantry in various combat situations. However, due to logistical and operational constraints, only 13 of these companies were deployed to Vietnam. This reflects the military's strategic decisions regarding troop deployment, resource allocation, and the evolving dynamics of the conflict in Vietnam.

Understanding the numbers behind the Ranger Companies highlights the characteristics of military organization and deployment during the Vietnam War, emphasizing that while many units were prepared, not all were sent to theater due to varying factors such as mission assignments, the requirement for specialized training, and the nature of the warfare at that time. This answer sheds light on the operational capabilities of the Ranger Regiment and their role in the broader context of the Vietnam War.
