The Army is not the nation's conscience keeper.
India's armed forces are as good, or as bad, as the rest of society.
Sometimes soldiers lie, cheat, steal, rape, pillage and run away in the face of danger. They mutiny, kill their comrades, betray their country and commit suicide. And sometimes, they also misuse privileges.
Any Army in the world, including the Indian Army, has such instances amongst its ranks. The key is to appreciate the infinitesimal occurrences in comparison with the rest of society, and the swiftness and severity with which the Army deals with such breaches.
