Actually, there was some specification, albeit imprecise. That specification was AIT, which as can be found through only a bit of searching, is prerequisite for the further training required to justify the claim in dispute.
Forgive me for repeating myself here, but it is only in response to your own repeating of vague assertions, which have been addressed, both in the previous posts to you on this subject, and again, more briefly in the paragraph above.
That info points toward both impossibility of the claim, and the futility of speculation towards it's support.
Three months is a little long for Infantry AIT, don’t you think?
