I've:
Forced doors
Vented roofs
Breeched walls/staircases from the inside
Taken windows/skylights
Pulled electrical meters before that became a no-no
etc.
all wit a Halligan
Give Me A Set Of Irons And Turn Me Loose. And We'll See How Fast Entry Can Be Made. They Didn't Call Us The Baboon Squad For Nothing Back In Trumansburg.
I like the good old "Try before you Pry" adage myself, but when it comes down to getting inside the "IRONS" really are great ! A well trained firefighter with a Flat Axe and Halligan can get into almost anything.
