Line of Control

Line of Control is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Line of Control rather than just read about it. In short: The Line of Control (LoC) is a military control line between the Indian- and Pakistani-controlled parts of the former princely state of Jammu and Kashmir—a line which does not constitute a legally recognized international boundary, but serves as the de facto border. It was established as part of the Simla Agreement at the end of the Indo-Pakistani War of 1971.

Reference excerpt

The Line of Control (LoC) is a military control line between the Indian- and Pakistani-controlled parts of the former princely state of Jammu and Kashmir—a line which does not constitute a legally recognized international boundary, but serves as the de facto border. It was established as part of the Simla Agreement at the end of the Indo-Pakistani War of 1971. Both nations agreed to rename the ceasefire line as the "Line of Control" and pledged to respect it without prejudice to their respective positions. Apart from minor details, the line is roughly the same as the original 1949 cease-fire line. The part of the former princely state under Indian control is divided into the union territories of Jammu and Kashmir and Ladakh. The Pakistani-controlled section is divided into Azad Kashmir and Gilgit–Baltistan. The northernmost point of the Line of Control is known as NJ9842, beyond which lies the Siachen Glacier, which became a bone of contention with Indian and Pakistani armed forces clashing there from 1984. To the south of the Line of Control, (Sangam, Chenab River, Akhnoor), lies the border between Pakistani Punjab and the Jammu province, which has an ambiguous status: India regards it as an "international boundary", and Pakistan calls it a "working border". Another ceasefire line separates the Indian-controlled state of Jammu and Kashmir from the Chinese-controlled area known as Aksai Chin. Lying further to the east, it is known as the Line of Actual Control (LAC).

Background

After the partition of India, present-day India and Pakistan contested the princely state of Jammu and Kashmir – India because of the ruler's accession to the country, and Pakistan by virtue of the state's Muslim-majority population. The First Kashmir War in 1947 lasted more than a year until a ceasefire was arranged through UN mediation. Both sides agreed on a ceasefire line. After another Kashmir War in 1965, and the Indo-Pakistani War of 1971 (which saw Bangladesh become independent), only minor modifications had been effected in the original ceasefire line. In the ensuing Simla Agreement in 1972, both countries agreed to convert the ceasefire line into a "Line of Control" (LoC) and observe it as a de facto border that armed action should not violate. The agreement declared that "neither side shall seek to alter it unilaterally, irrespective of mutual differences and legal interpretations". The United Nations Military Observer Group in India and Pakistan (UNMOGIP) had the role of investigating ceasefire violations (CFVs), however their role decreased after 1971. In 2000, US President Bill Clinton referred to the Indian subcontinent and the Kashmir Line of Control, in particular, as one of the most dangerous places in the world.

Characteristics

Terrain The LoC from Kargil to Gurez comprises mountain passes and valleys with small streams and rivers. The area up to around 14,000 feet (4,300 m) is wooded while the peaks rise higher. Winter is snowy while summers are mild. From Gurez to Akhnoor, the area is mountainous and hilly respectively and is generally forested. There are tracks and minor roads connecting settlements. The mix of flora and elevation affects visibility and line of sight significantly.

Ceasefire violations In 2018, two corps and a number of battalions of the Border Security Force manned the Indian side of the LoC. The Rawalpindi Corps manned the Pakistani side. Ceasefire violations (CFV's) are initiated and committed by both sides and show a symmetry. The response to a CFV at one location can lead to shooting at an entirely different area. Weapons used on the LoC include small arms, rocket-propelled grenades, recoilless rifles, mortars, automatic grenade launchers, rocket launchers and a number of other direct and indirect weaponry. Military personnel on both sides risk being shot by snipers in moving vehicles, through bunker peepholes and during meals. The civilian population at the LoC, at some points ahead of the forward most post, has complicated the situation. Shelling and firing by both sides along the LoC has resulted in civilian deaths. Bunkers have been constructed for these civilian populations for protection during periods of CFV's. India and Pakistan usually report only casualties on their own sides of the LoC, with the media blaming the other side for the firing and each side claiming an adequate retaliation. According to Happymon Jacob, the reasons for CFVs along the LoC include operational reasons (defence construction like observation facilities, the rule of the gun, lack of bilateral mechanisms for border management, personality traits and the emotional state of soldiers and commanders), politico-strategic reasons, proportional response (land grab, sniping triggered, "I am better than you", revenge firing), accidental CFVs (civilian related, lack of clarity where the line is) and other reasons (like testing the new boys, honour, prestige and humiliation, fun, gamesmanship). Jacob ranks operational reasons as the main cause for CFVs, followed by retributive and politico-strategic reasons .

Landmines and IEDs Mines have been laid across the India–Pakistan border and the LoC in 1947, 1965, 1971 and 2001. The small stretch of land between the rows of fencing is mined with thousands of landmines. During the 2001–2002 India–Pakistan standoff thousands of acres of land along the LoC were mined. Both civilians and military personnel on both sides have died in mine and improvised explosive device (IED)-related blasts, and many more have been injured. Between January 2000 to April 2002, 138 military personnel were killed on the Indian side.

Posts and bunkers Reinforced sandbagged and concrete posts and bunkers are among the first line of defence along the LoC. Armed soldiers man these positions with enough supplies for at least a week. The posts and bunkers allow soldiers to sleep, cook, and keep a watch on enemy positions round the clock. Some posts are located in remote locations. Animals are sometimes used to help transport loads, and at some posts animals are reared. The living quarters and the forward facing bunker are located at some distance apart. The locations of some posts do not follow any pre-ordained plan, rather they are in locations used during the First Kashmir War and the following cease-fire line, with minor adjustments made in 1972.

Worked examples

Example 1 — a first encounter with Line of Control

Start with the simplest possible case. Write down what Line of Control claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Line of Control before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Line of Control ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Line of Control

In research: Line of Control appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Line of Control in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Line of Control is common in secondary-school and first-year university syllabi. It links to neighbouring topics History of Azad Kashmir, History of Gilgit-Baltistan, History of the Republic of India, so understanding it makes those chapters shorter.
In everyday life: Look for Line of Control outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
