Heavy Industries Taxila (abbreviated HIT) is the backbone of Pakistan's engineering industry for the Pakistan Armed Forces, being a combination of multiple industries that has grown into a large military complex since 1980. It consists of six major production units and their support facilities, staffed by over 6500 workers. About 30% of the 6500 employees are uniformed military personnel.

HIT has facilities for overhaul, rebuild and progressive manufacturing of main battle tanks (MBT), armoured recovery vehicles (ARV), armoured personnel carriers (APC) and other armoured vehicles of both eastern and western armoured vehicles. HIT has developed and currently manufactures the Al-Khalid MBT.

With the growing fleet of T-59 tanks manufactured by China, the Pakistan Army decided that a facility to maintain and rebuild the tanks was needed. As a result the Heavy Rebuild Foundry Project (P-711) was conceived, with Chinese assistance and technology. In the late 1970s the Heavy Rebuild Factory (HRF) was established in Taxila to undertake rebuild and modernization of tanks.

Taxila (Urdu: ٹیکسلا) is a Tehsil in the Rawalpindi District of Punjab province of Pakistan. It is an important archaeological site. Taxila is situated about 32 km (20 mi) northwest of Islamabad Capital Territory and Rawalpindi in Panjab; just off the Grand Trunk Road. Taxila lies 549 metres (1,801 ft) above sea level.

The city dates back to the Gandhara period and contains the ruins of the Gandhāran city of Takṣaśilā which was an important Hindu and Buddhist centre, and is still considered a place of religious and historical sanctity in those traditions. In 1980, Taxila was declared a UNESCO World Heritage Site with multiple locations. In 2006 it was ranked as the top tourist destination in Pakistan by The Guardian newspaper.

Scattered references in later works indicate that Takshashila may have dated back to at least the 5th century BCE. Takṣaśilā is reputed to derive its name from Takṣa, who was the son of Bharata, the brother of Rama, and Mandavi. Legend has it that Takṣa ruled a kingdom called Takṣa Khanda, and founded the city of Takṣaśilā. According to another theory propounded by Damodar Dharmanand Kosambi, Takṣaśilā is related to Takṣaka, Sanskrit for "carpenter", and is an alternative name for the Nāgas of ancient India.

Heavy industry does not have a single fixed meaning as compared to light industry. It can mean production of products which are either heavy in weight or in the processes leading to their production. In general, it is a popular term used within the name of many Japanese and Korean firms, meaning 'construction' for big projects. Example projects include the construction of large buildings, chemical plants, the H-IIA rocket and also includes the production of construction equipment such as cranes and bulldozers. Alternatively, heavy industry projects can be generalized as more capital intensive or as requiring greater or more advanced resources, facilities or management.

Heavy industry is often defined as a type of business that typically carries a high capital cost (capital-intensive), high barriers to entry and low transportability. The term "heavy" refers to the fact that the items produced by "heavy industry" used to be products such as iron, coal, oil, ships, etc. Today the reference also refers industries that cause disruption to the environment in the form of pollution, deforestation, etc
