The esteemed Dr. Christopher E. Larsen discusses the military training open to civilians:
While some of the video certainly promotes the training offered at One Shepard, he proposes an noteworthy list of required competencies and training:
Is Military Training Open to Civilians?
While I would agree with him to an extent that it is an issue when some people who prioritize marksmanship to the detriment of all other competencies, and that tactics and Force-on-Force are critical, I wonder what everyone else thinks about it? What are the required competencies and training? What are good places for a civilian go to get them?
I once had a General with nearly 40 years in the infantry tell me that while command talks about all kinds of things, at the end of the day hitting your target when you needed to was the most important thing.
Fitness, Medical, Marksmanship, Tactics, Comms, and Land Nav are core competencies. Leadership training and combatives are well worth having. Some of those things are mentioned in the video, some are not directly mentioned.
I always worked to get fellow soldiers into climbing, as an activity climbing is ideal for developing fitness and mindset.
