The Actual Ground Position Line (AGPL) divides current positions of Indian and Pakistani military posts and troops along the entire long frontline in the disputed region of Siachen Glacier.The fight for SiachenThey shall not pass AGPL generally runs along the Saltoro Mountains range, beginning from the northernmost point of the (LOC) at Point NJ 9842 and ending in the north on the Indira Ridge at the India-China-Pakistan LAC tripoint near Sia Kangri about northwest of Indira Col West, with peaks in excess of and temperatures ranging to around . India gained control of of disputed territory in 1984 because of its military operations in Siachen. A cease-fire was announced in 2003.

India has at least 108 forward military outposts and artillery observation posts in this area where temperature goes down to during winters with icy 100 km/h () blizzards.Bana Top () is the highest post and requires an trek that takes up to 20 days for troops to reach. Pahalwan Post (), and Indira Col (), are other high posts. India has two major bases, each with a brigade strength of five to eight battalions supported by additional artillery, air defence, engineer and other logistic units: Thoise which serves the southern Siachen sector, and Siachen Base Camp which serves the northern and middle sectors of Siachen. Kumar Post, a logistics subbase of Siachen Base Camp, is a 9-day return trek from Siachen Base camp towards Indira Col.Siachen Glacier open to tourists! Everything you must know before visiting world’s highest battlefield, Financial Express, 26 October 2019. India has significant tactical advantage as it occupies most of the higher peaks on the Saltoro Mountain Range in the western sector of Siachen. The Pakistani Army hold posts at lower heights on the western slopes of the spurs of the Saltoro Ridge. Pakistan has not been able to scale the crest of the Saltoro Range occupied by India. Each post has an artillery officer who are deployed in the rotation of 45 days.Haryanvi Meghdoot who defended the most challenging post in Siachen, The Tribune, 9 Nov 2019. The average temperature is between minus 25 °C during day and minus 55 °C during the night.Everyday is a story: Army officers recall their time at Siachen Glacier, Indian Express, 14 Feb 2016. As of 2013, Siachen operations cost INR 3,000 crore annually where over 850 Indian and over 1,800 Pakistani soldiers have died, mostly not in combat, but due to the weather conditions.

The actual India-Pakistan boundary is divided into four types of borders: disputed Sir Creek (SC) riverine border, mutually agreed India–Pakistan International Border (IB) from north of Sir Creek to north of Dhalan near Jammu, LoC across disputed Kashmir and Ladakh regions from north of Dhalan in India and west of Chicken's Neck in Pakistan to Point NJ9842, and Actual Ground Position Line (AGPL) across Siachen from Point NJ9842 to Indira Col West. Siachen lies south of the Shaksgam ceded by Pakistan to China via the 1963 Sino-Pakistan Agreement but also claimed by India and Aksai Chin held by China since 1962 but also claimed by India. The Shaksgam Tract, controlled by China, is located north of the Saltoro mountain range from the Apsarasas Kangri Range to northwest of K2.R Baghela and M Nüsserab, 2015, Securing the heights: The vertical dimension of the Siachen conflict between India and Pakistan in the Eastern Karakoram, Political Geography (journal), Volume 48, Pages 24–36.

AGPL details

AGPL alignment

AGPL alignment, from south to north, runs near the following features of the Saltoro Mountains subrange of Karakoram: AGPL runs through the western side of the Saltoro Mountains Range, of which western slopes are held by Pakistan and separated by the AGPL the higher peaks and passes are held by India - all of which remain snowbound throughout the year. Five passes in the Saltoro Mountains Range provide access to Siachen Glacier to its east, i.e., listed from south to north are Chulung La (5,800m), Yarma La (6,100m), Gyong La (5,640m), Bilafond La (6,160m) - also called Saltoro La, and Sia La (7,300m).Ghazanfar Ali and Hassan Akhtar Ghani, Siachen-The world's highest battlefield; Military Technology; Bonn Vol. 22, Iss. 3, (Mar 1998): S15-S17. To the east of AGPL is Siachen Glacier which falls from the height of 18000 ft at Indira Kol to nearly 11000 ft at its terminus near India's Siachen Base Camp. India and Pakistan have nearly 150 military posts in Siachen along AGPL with nearly 3,000 soldiers each. Nearest road is to the Indian Military Base Camp at Dzingrulma, with 5G mobile and internet connectivity, which is 72 km from the beginning of the Siachen glacier at Indira Col. Nearest civilian village is Warshi in India, 16 km (10 miles) downstream from the Indian base camp on the Dzingrulma-Khalsar Road.

Trans-Karakoram LAC alignment

While AGPL runs through the Saltoro Mountain Range, the line which separates disputed China-held Trans-Karakoram Tract (also called Shaksgam Valley, gifted by Pakistan to China and also claimed by India) from the India-held Siachen area runs through the following features of Karakoram range as follows (from west to east):

Indira Col Turkestan La, Turkestan La North and Turkestan La East. Singhi Kangri (7,202 m or 23,629 ft). Teram Kangri I (7,462 metres or 24,482 feet), Teram Kangri group is a mountain massif in the remote Siachen Muztagh subrange of the Karakoram range, Teram Kangri I is the highest peak.

Military posts along AGPL

India maintains at least 108 forward military outposts and artillery observation posts along the Actual Ground Position Line (AGPL), which runs along the Saltoro Ridge. Pakistan has around 50 posts, mostly at lower elevations west of the Saltoro ridge. Some of the well-known bases and posts are:30 years of the world's coldest war, The Tribune, 13 April 1984.
