Soldiers closing the gates of hell

[Chaz]

I am looking for a book, it might be a comic book, about the gates of hell opening on earth. Soldiers are assigned to close the gates, but it can only be done from the inside, locking themselves in hell. Any help is appreciated, thanks.

Chaz, around what year did you read this book? A range of years is fine.

Can you describe the main character(s) and who they work for?

Is this book (or graphic novel) for teens or adults?
