This is why you research BEFORE you start writing

I thought that because it sounds cool, 'Lance Corporal' was a higher rank than it actually is. So Lori's getting a promotion For those of you who don't know, LCpL is two higher than Private, which isn't all too impressive. So Lori's now going Master Gunnery Sergeant (MGySgt). This change is mostly because she did what she did for fucking ages, and it was just sorta unrealistic that she'd stay so low down for nine years - I'd always had her down as something high up, this is just a case of me not doing my research properly beforehand. So now I need to go reread anything she's been in and change that
Hasta la vista, kids,
