Twelve US A-10C Thunderbolt II attack aircraft were spotted landing at RAF Lakenheath in England on Monday. Commonly described as 'tank buster', the aircraft is designed to support ground forces in combat, and its signature weapon is GAU‑8/A Avenger cannon, a seven‑barrel Gatling gun, which can fire up to 3,900 rounds/minute. This comes amid a possible ground invasion in Iran.
