A video release by one of Pakistan's Baluchistan separatist groups reportedly shows a Jan. 20, 2021 improvised explosive device attack on a Pakistan military technical truck, resulting in a catastrophic loss of the vehicle and all its occupants.
Up until recent months, the Baloch rebel videos showed attacks almost exclusively limited to linear and L-shaped ambushes, using small arms and sometimes RPG's. However, a recent shift in tactics has now shown a focus on the use of IEDs. The use of roadside bombs allows smaller, less detectable groups of insurgents to carry out equally deadly attacks on enemy units while reducing the risk of friendly casualties.
The video starts with the separatist insurgents prepping the device, which appears to be an anti tank mine hull packed with some sort of malleable explosive substance. Also pictured is some very new-looking bright orange detonation cord. Sometimes the source of the det cord can be deduced by its color... i.e. the US may produce green cord and the Russians may produce red. It is possible that the orange cord could be a product out of India.
While we don't know where the insurgents are getting their new supplies and training to implement them, it looks like some of the techniques may be organically developed. In the video, we can see several feet of the det cord erupt in the foreground of the target shortly before the main payload explodes. I don't recall seeing that in any other video over the years. Maybe they didn't want the ignition device, possibly a walkie talkie that would need it's antenna exposed to reliably receive the burst command, to be detected, so it was placed away from the actual explosive ordnance, and the length of det cord would only require a negligible amount of time to reach the mine and detonate it.
The insurgents claim 11 Pakistan soldiers were killed in the attack, but that number may be inflated and cannot be confirmed from the video alone. The video does show repeated use of the same travel way by the Pakistani military units. Their predictability makes them easy targets, and large devices can be easily and rapidly hidden in the non-paved driving surface.
