HTS meaning in Military and Defence ?

The Human Terrain System (HTS) was a United States Army, Training and Doctrine Command (TRADOC) support program employing personnel from the social science disciplines – such as anthropology, sociology, political science, regional studies, and linguistics – to provide military commanders and staff with an understanding of the local population (i.e. the "human terrain") in the regions in which they are deployed.

The concept of HTS was first developed in a paper by Montgomery McFate and Andrea Jackson in 2005, which proposed a pilot version of the project as a response to "identified gaps in [US military] commanders' and staffs' understanding of the local population and culture", such as became particularly visible during the US invasion of Iraq and Afghanistan. HTS was subsequently launched as a proof-of-concept program, run by the United States Army Training and Doctrine Command (TRADOC), in February 2007, with five HTS teams deployed between Iraq and Afghanistan. Since 2007, HTS has grown from a program with five deployed teams and a $20 million two-year budget to one with 31 deployed teams and a $150 million annual budget. HTS became a permanent US Army program in 2010.

Ever since its launch, HTS has been surrounded by controversy. While the program initially received positive coverage in the US media, it quickly became the subject of heavy criticism – particularly from anthropologists, but also from journalists, military officials and HTS personnel and former personnel. Most notably, on 31 October 2007, the Executive Board of the American Anthropological Association (AAA) published a statement opposing HTS as an "unacceptable application of anthropological expertise" that conflicted with the AAA's Code of Ethics. Following the publication of a report on HTS by the Commission on Engagement of Anthropology with the US Security and Intelligence Services (CEAUSSIC) in 2009, the AAA released a further statement of disapproval, which they re-iterated in 2012 after rumours that the controversy had died down.

The program evolved into a mechanism for supporting security force assistance. The program ended operations on 30 September 2014.
