Iran shoots down US MQ-9 Reaper. How different are India-operated MQ-9 drones?

Iran’s Islamic Revolutionary Guards Corp shot down an American MQ-9 Reaper drone over the Strait of Hormuz on Monday. The aircraft fell into the Persian Gulf after being hit by missile fire. India operates a different variant, the MQ-9B Sea Guardian, which is designed for long-range maritime reconnaissance missions instead.
