Perhaps the lack of overt support for an e-petition is a case of:
1. Military types being institutionally cautious about e-petitions.
2. Military types knowing that wrt actually having the desired effect an airing in The House is as likely to succeed as a Baghdad paper round.
3. Military types instead joining the AFPS as a means to ensure that someone knowledgable is fighting their cause.
4. We're all actually waiting to see what the initial document says, after all, you can't fight what you can't see.
