I was a Helicopter Crew Chief in the Marines and I'm sure the Regulator will not fit in the designated survival knife area on the flight vest, but things have probably changed. I'm sure she'll find something to do with it.
Congrats HD!
Right you are, Spider-pig. She may have to make do with a brand new Scrapper 5, instead. She has a YKLE and a RC-4. But she will still get the Regulator for her collection.
