In all the excitement of recreating a major historical event, don't you think that the director or anyone involved could have done a basic research on the naval uniforms of both sides - at least the difference between those of Officers and Men. Here the Indian officers are seen with their shoulder boards as well as insignia of sailors. Commander of the boat also has a Petty Officers arm badge. Engineering, communication and other officer ranks also messed up. Plots shamelessly copied out of Crimson tide, Das boot, U 571 and Hunt for red October to name a few that I have watched. Why do they have to show the opposite number captain as "angry". The creators of such movies should stop taking us audience for granted
