Your assesment about the presence of mistral missiles on the Dhruv appears correct, but the following statements mention a quad mistral system :-
"The Army has also decided to arm the ALH Dhruv with a
quad MBDA Mistral missile pod, a 20 mm
gun from GIAT, rocket pods from FZ
Belgium and with Israeli EW equipment at
Hindustan Aeronautics Ltd (HAL)."

It maybe possible that a dual-mistral launcher may have been selected. Also, the author of the article posted by me, is Major General (retd) Ashok K Mehta, who is a defence columnist. His article about the Dhruv at Farnborough 2006 does not mention the Mistral, but the LAHAT. Can it be possible that a dual Lahat launcher has been developed ?
