राहत और बचाव के लिये सेना, आईटीबीपी ,बीआरओ और एनडीआरएफ की कंपनी तैनात हैं. This is from a text on the terrible floods in Northern India. I have understood that divisions of the army and the ITBP - the Indo-Tibetan Border Police - have been sent to the area to help and rescue the people there. But I am at a loss for the other two rescue teams. Google didn't help, that's why I'm asking you to please help and give the full form of the abbreviations BRO and NDRF. Thank you very much.
