Hi,
The scammers have West-African local names, thus the diplomat is a fake sender.
Either candy/flowers/a small teddybear (paid for by stolen CC info), or something (anything, can be electronics, expensive trainers, from online shops, paid for by stolen credit card) with a request to re-ship to his "commander"/"relative"/"local driver"/"son" in West-Africa.
Not familiar with US military but I assume it would be shipped/mailed by an US Army owned service, which would definitely be reflected on the package.
I think it´s better not to accept it and to simply become quiet on the scammers and not answer questions
