Why not take a positive lesson from Sri Lanka rather than Pakistan?
Remember Naxalite movement isn't about freedom; it is also no longer about land allocation; it is lust for power.
Comparing Pakistan's situation to ours is simply foolish. The nature of trouble there funnels from something else while the Naxal problem has nothing to do with a problem of that nature.
It is no longer a force 'for the poor'.
It has morphed into a terrorist organization that kills not just troops but also civilians.
The intentions of the outfit (whether they are working for the pooor, or to grab power for themselves) is not the criterion. The armed forces themselves have been very apprehensive about being deployed in CI missions against Maoists, and for good reason - they will lose their warfighting skills if they are mired in CI. That is why the regular army doesn't even do CI against Kashmiri terrorists, and raised a separate force (RR) for the same.
Besides, tanks, arty and airpower can do nothing if you don't know where to drop the bombs. If the enemy lives among the people in civilian clothes, airpower or tanks cannot differentiate friend from foe. These maoist cadre, in their regular hours, work among the population. They are not a conventional army wearing uniforms and holding static lines. If that was the case, gunships and arty can pound their positions. But for geurilla warfare within our territory, the only way to counter it is the way we are doing.
Also, calling the army for internal duties is a slippery slope. Do you want govts to have that power? In future, if a govt in power uses the armed forces to crush political opposition, would you be OK with that?
As for SL, note that the 4th ealam war was a conventional war - the LTTE was ruling the east of SL. They had their own armed forces, area under their control, civil administration etc. It was a war between west SL and the easternmost part, so to speak. The LTTE was not living among Sri Lankan population and doing guerilla war.
If Andhra had pussyfooted like how Chhatisgarh, Bihar and Jharkhand are doing, then they would have never let Greyhounds brutally finish off Maoists in their state.
And there you have it - it is a unit of the state police that eliminated naxalism, not tanks or airpower.
An NDTV show about the topic. As I expected, the country is more outraged by the insult to the uniform, than the deaths of 16 policemen:
