Pentagon amends M-ATV solicitation--answer to Navistar objection?

InsideDefense reports (subscription only!) that the M-ATV solicitation has been amended to more specifically define "hull breach."

This, of course, will fuel speculation that the amendment follows from Navistar's recent protest of the M-ATV competition.

Consider this post part of the vanguard of that speculation. I don't know if the InsideDefense report makes the connection, by the way.
