これはいったい何の集会？

質問：本日、元海兵３等軍曹（私）、３等空曹、元海兵２等軍曹、大佐、１等陸佐、そして公務員が集まります。さて、いったい何の集まりなのでしょうか？ (*_*)

答え：…ただの食事会です。しかし名前ではなく肩書きだけだと、なんかの日米合同訓練・会議・イベントなどに見えるのは、私だけ？ ではもう少ししたら行ってきます！(>_<)

What kind of meeting is this anyway?
Question: Today, a former Marine Sergeant (me), a JASDF Sergeant, a former Marine Staff Sergeant, a Colonel, a JGSDF Colonel, and a Japanese federal employee will be meeting up. So, kind of meeting is this? (*_*)

Answer: ...It's just a dinner engagement. Am I the only one, after looking at the job titles and not names, gets the impression that this seems like some sort of US-JPN bilateral training/conference/event/etc.? Oh well, I'll be taking off in a few! (>_<)
