Whether or not it warrants payment is an entirely separate matter from how it looks. The fact is that as the 3rd woman to complete Ranger School, she has more of a responsibility to set the example. Immediately seeking to cash in, while not inherent illegal, is certainly unseemly and distasteful. Maintaining a quiet professionalism and offering to help women wanting to walk her path is one thing, running to the bank with a fistful of cash is quite another.
I'm not saying there would be anything inherently wrong with it. What I am saying is that your leadership at 3/75 likely would have had a strong conversation with you had you decided during your first month at Regiment to write a book about training. They may have colorfully suggested you focus on learning the job and being as grey as possible. Do you disagree? She should use her experience to help other women, but I strongly disagree with this move. It's unprofessional, attention-seeking, and selfish.
What is "setting the example" is up for interpretation, I suppose. If we were to disagree with anything, it seems to lie on this issue. It could be argued that since she is one of the first, she is obliged to share her experience, thereby motivating more women and men to aim high. I'm not saying this is my view, I just see it as not so clear. Again, a quiet professionalism could recruit fewer people to walk her path. She isn't in the CIA or under NDA, so I see little distasteful about it. If it were proven her motives for Ranger School were to make a "fistful of cash", I would see this as unseemly, just as you do. I would just like evidence of such motives.
I think being in a Special Operations unit (with my tiny bit of experience), is different. Again, I am amateur hour compared to the great people we have on this forum. However, I think what SOF does as a
job, is in fact, different from a leadership course or military school. While there might be similarities, the responsibilities of both respective groups (SOF and MIL school attendees) are not similar. I agree with you about what leadership in Batt might say, but, it's because of the nature of the job. By wanting to be assessed and selected by certain organizations, I would argue you give up your right to do certain things. I simply don't extend this obligation to most military schools. Schools with NDA's and "critical/mission essential information" seem to fit the "don't talk about this" side of the argument.
I think her experience can be used to help many people, not just women. Probably very few on this forum, but I doubt her talks would be for people like us.
Note: I suppose it's important to note I am fairly biased. My whole career was started because of books from SOF veterans...some vetted and some not. Either way, I was inspired and still am.
