Broadsword (Col Ajay Shukla) has asked contributions on Tank designs for future in his blog here: Broadsword: The Great Indian Tank Design Challenge I have contributed my vies as follows: Have a look at the Borders of India Bangladesh 4,053 km (No Tanks) Bhutan 605 km (No Tanks) Burma 1,463 km (No Tanks) China 3,380 km (No Tanks) Nepal 1,690 km ( Very limited application) Pakistan 2,912 km (applicable south of Jammu till Bhauj in Gujrat say about 2020km) Border areas opposite Jammu (IB portions) and Punjab have been rendered untankable by obstacles and built up araes on both sides besides being untankable in raiany season. Hence 763 km length is you can say semi tankable. Opoosite a half of Rajasthan say 500 km in the north, tanks can barely go upto 20 km. Same is the terrain conditions opposite rest of Rajstan and Gujrat. Both sides of the borders are heavily guarded and have dense anti tank military opposition. Above all, all areas are astride the settled IB. Neither Pakistan nor India would unsettle it. Use of tanks would necessarily be under nuclear hang and hence less likely. In nutshell heavy or medium tanks are primarily Pakistan specific and must remain focused on Pakistan amour rather than on the world or any other border areas. At present what ever India has is sufficient to cater for "Need Pakistan" and bogey of tanks being raised is pseudo. Arjun Mark II will be sufficient till Pakistani armour profile changes. India now needs a tank which can be employed in: Riverine terrain. Jungles of middle India Jharkhand / Chattisgarh. Mountains. Tibet. UN missions and out of Area contingencies. Amphibous operations. Urban areas. What kind of anti tank environments exist in those areas and under those contingencies? Many here are designing a tank to fight a NATO war in Europe or for the Western Russia ?? How useful the heavy tanks been in fighting terrorists in Iraq and Afghanistan? We need now a 30 ton light tank (call it infantry tank) capable of carrying troops in large numbers to meet our above requirement. In that following should be order of priority: Fire power, then Mobility, and then Amour protection It can not and should not something like a BMP but like Stryker ( or a mix of wheels and tracks) India otherwise has sufficient tanks of required quality. This tankman's bogey is false and self serving. Tank philosophy, Mission profiles, operations planned and envisaged in India and Pakistan are exaggerated and impractical.
