This is what needs to be done,
1. Build much better infrastructure (highways) to Bandarban, Rangamati and Khagrachhari. Build new patrol roads and settlements in the border areas to patrol the border more intensely. Much more than today.
2. Build large airbases in all the larger towns in the Hill tracts, so intensified air-patrols can take place using manned and drone patrol aircraft. Conduct intensified air patrols. Much more than today.
3. Procure AC-130H Ground-attack aircraft/close air support gunship as well as other smaller COIN aircraft platforms to counter any insurgent activity (Embraer Tucano type slow prop driven aircraft) which can use guided and unguided rockets and other locally made economical cost effective air-launched munitions to 'soften' insurgent targets.
3. Take people from Chittagong and Noakhali to the border area settlements and give them enticement to settle there (low cost agricultural land to farm coffee, coco, tea, pineapple, bananas and whatever else). Talk with the agri-dept. and come up with new crop plans in these areas.
4. Develop tourism in areas other than Sajek Valley. Ensure safety with military patrols.
5. Work intensely with Tribal elders/chiefs and ensure misunderstandings between tribals and Bangladeshis are avoided. This is of utmost importance.
6. Ensure tribals learn Bangla and use it in govt. and educational usage and encourage inter-marriage between tribals and Bangladeshis.
