If so, you’ll want to read all of Shashank Joshi‘s recommendations (full disclosure … I haven’t actually read any of the linked sites myself):
Peter Mattis’ explanation of what one should read to be an expert on China’s People’s Liberation Army (PLA) made me wonder: What might a similar list look like for India-watchers? Western interest in India’s armed forces is considerably slighter, largely because India looms far smaller in U.S. strategic thinking and is viewed as a potential partner rather than probable military adversary. But there’s a large and growing volume of writing on Indian military affairs, almost all of it in English, with cutting-edge books or articles appearing every month. So where should one begin?
Each service has its own doctrine and/or strategy — most recently the army in 2004, the navy in 2009 (remarkably, it is not available online), and the air force in 2012 (the official link is — perhaps aptly — perpetually broken, but you can get it here) — but these are of limited use, not least because they’re not written in close coordination with other services or with a coherent national military strategy in mind. So most analyses depend on secondary texts, occasional statements by serving officers, and writing by retirees.
