Personally speaking, some of the skills that I took that were directly transferable to the civilian and entrepreneurship world are organization and leadership. We're very well-equipped in the military, especially as officers. That, coupled with my trade as a logistics officer.... I took a lot of directly relevant skills, such as accounting and human resources.
For me, personally, a lot of my job skills in the military directly correlated to entrepreneurship. However, I think the leadership piece and the community piece are the pinpoint of the skill set that military people can offer entrepreneurship.
