The Indian Army will develop underground facilities for the storage of ammunition at forward locations along the Line of Actual Control (LAC), build a slew of new roads, bridges, and tunnels as part of an overarching infrastructure push to strengthen its capabilities in the sensitive sector, and build modular, 3D-printed, next generation bunkers to better protect front-line soldiers guarding the country's border.

According to one of the individuals described above who monitors infrastructure construction in forward areas, the modern bunkers, which the army refers to as 3D printed permanent defences, will appear near LAC starting in 2019 and will be able to withstand a direct hit by a tank shell. They are manufactured with a special type of quick-drying concrete and additive, and they are 3D printed, hence their name.

The US army, for instance, has been building bunkers with 3D printers for at least a few years.
