IDF "Roof Knocking" | Get the hell out of there
What is ‘roof knocking’?
Israel fires “warning rockets” – often sent from drones – to alert residents that a building is to be targeted. The Israel Defense Forces (IDF) call the technique “roof knocking”, and claim it is a “time-tested strategy”.
The warning rocket has no warhead, and is meant only to shake the building before armed missiles hit it three to 15 minutes later. The Israeli military has deployed the tactic during its bombing of Gaza in recent days, including its strike on a 13-storey residential building in Gaza City.
