What is the thinking behind "sentry gen". After doing research, I don't see much

(Only "sentry" and "sentry gun")

It could be used for below.
Sentry Genetics
Sentry Genomics
Sentry Genesis
Sentry Generation
etc.

@monotheist I've Googled every one of those things, and I see no real world meaning for them. No wiki, no definitions, no credible source ...unless you can show me

I can't place them ...overall, its a struggle value wise. Sorry
