25 CRPF jawans were martyred in one of the deadliest Naxal attacks in Chhattisgarh's Sukma district. Reacting to the reports, Prime Minister Narendra Modi said "the sacrifice of the martyrs will not go in vain." While India is mourning the death of its brave-hearts, Sukma continues to remain a death trap for security personnel posted in the area. Security forces have faced a series of encounters and deadly ambushes over the years and this has turned the region into a hotbed of naxalism. Previous incidents of attacks carried out against security personnel and subsequent investigation reports have often revealed that these acts were "pre-planned" and executed with "deadly accuracy". Yes numerous ultras have also been arrested from the area, but it's image of being a dangerous area to be in looms large. Yesterday's incident has once again raised the question, what really makes Sukma the place where Naxals can operate at will. In earlier attacks, often it was found that the security forces seemed to have walked into a trap. They were surrounded by naxals who unleashed the attack. Forces do retaliate but by then quite a few of the security personnel have been injured and casualties reported, according to PTI reports. Watch this video It has been learned that Naxals are well armed with automatic weapons to take on the security forces - in Monday's attack, the Naxals were reportedly carrying AK-47s and even a rocket launcher. But one thing that makes the biggest difference is the geographical advantage that the ultras have on their side. It is their supreme knowledge of the topography, which is extremely difficult, that seems to give them a supremacy during such encounters. They are using this ground knowledge as a potent weapon, PTI reports say. Over last few years, one of Chhattisgarh government\u2019s attempts to break the Maoist dominance in Sukma district has been to focus on laying down of roads. The state government is trying to do this by connecting Jagargunda with Dornapal in the east, Bijapur in the west, and Kirandul in Dantewada in the north. All three roads are under construction. The stretch on which the Maoists ambushed the CRPF patrol team on Monday is one of those crucial under-construction roads in south Sukma, one of the most Maoist violence-affected areas, as per the Indian Express report. Over the last three years, road-building activity in this area has seen 11 exchanges of fire, 18 IED blasts, three civilian deaths in explosions, and the recovery of 16 IEDs, the report says.
