Now a map of Asia, with China in red and India in blue, zooming in slowly on the border region between them in the Tibetan plateau. As it got closer, Laks was able to pick out the bent Chinese salient that had come to be known as the Yak’s Leg, crossing over the long boomerang-shaped lake of Pangong Tso (right now they were only a short distance west of the "knee" in the leg, above the lake’s northern tip). A simple animation showed the border moving this way and that, like a sail luffing in the wind. Old grainy footage of Chinese and Indian military units trudging through snow and shooting rifles completed the picture. Shooty and explody sound effects echoed harshly from the hard floor of the room. But then suddenly it went silent, except for an old-time trumpet fanfare. In huge black numerals, "1962" covered the map. The red/blue frontier froze. An animated line snaked along the boundary and a label appeared: LINE OF ACTUAL CONTROL. "The cease-fire of 1962 put an end to armed conflict between India and China along their shared border—which remains disputed to this day. A peace agreement signed by Zhou Enlai and Jawaharlal Nehru referred not to the border but to the Line of Actual Control—a diplomatic phrasing that enabled the cease-fire to be formalized without either party acknowledging the other’s territorial claims." This bit was helpfully illustrated by stock footage of the respective leaders inking documents. "Since 1962 the position of the Line of Actual Control has shifted this way and that. However, the cease-fire itself—the mutual agreement not to use firearms—has remained as perfectly unbroken as mankind’s collective agreement not to use nuclear weapons. Three-quarters of a century has passed without a bullet disturbing the high mountain border zone. This in spite of the fact that it is heavily militarized on both sides by units of the Indian and Chinese military. This does not, however, mean that no conflict has taken place in the area—only that no firearms have been used. Occasionally, patrolling units of the two opposing sides have come into direct contact in areas where the exact position of the Line is not precisely charted. Indian military has respected the Line but Chinese have taken advantage to make small invasions of Indian territory. Added up over time, if allowed to endure, these move the Line, causing major loss of strategic high ground to our aggressive neighbor to the north. How to punish the invaders and move them firmly back to where they belong, while still preserving cease-fire? With sticks and stones, and, if need be, fists. Incidents of this type, once rare, became common in first decades of the twenty-first century. It is not known when volunteer units first began to arrive at the front. Now it is commonplace on both sides. By stepping out yonder door you are entering a zone of low-intensity but very real warfare that can become a hot shooting war at any moment should a combatant on either side discharge even a single bullet from a firearm. We, the men and women of the Indian Army, welcome volunteers from all over our great country, and indeed the world, who come to this place to push back the invaders and stabilize the Line in its rightful spot. However, we must always be on the alert for hotheads who do not respect the rules, or foreign spies who would seek to infiltrate volunteer ranks in the role of agent provocateur. Hence the procedures enacted in this facility. Thank you and good luck in your adventures at the front!"
