Prior to the 1990s it was a paramilitary Israel Defense Forces program that combined military service and the establishment of agricultural settlements, often in peripheral areas.
Today, a gar'in is usually a group formed by a youth movement, such as the Israeli Scouts, for the purpose of volunteer work.
The first is a large, non-combat command belonging to the IDF Education Corps, whose primary responsibility is to organize and coordinate the volunteer-type programs and activities that made the original Nahal unit famous in the 1950s, 1960s, and 1970s.
The national mission period lasts a year, in which all the core group stays together, under the command of the Education and Youth Corps.

[10] In the 1960s there was an Israeli aid project for developing countries, in Africa, Asia and South America, with the help of the Nahal Corps.
This project helped create the international image of the State of Israel, and opened the door to economic and security cooperation.
John Tatega, the secretary general of the trade unions in Guinea, showed interest in the Israeli army and its methods for making the desert flourish, and following negotiations, a delegation of four Israeli Nahal officers was sent to Guinea who helped to establish similar units in the Ghanaian army organized in a divisional framework called the "Builders Brigade".
John Tatega was at the head of the framework and on the recommendation of the Israelis he received a rank equivalent to lieutenant colonel.
Dozens of Israeli Nahal delegations participated in the project that began in Guinea and continued in Kenya, Tanzania, Zambia, Malawi, the Ivory Coast, the Central African Republic, Chad, Cameroon, Togo; and outside Africa: Iran, Singapore, Ecuador, Bolivia and more.
The Nahal's activities abroad and on the international level largely ceased due to the deterioration of Israel's political relations after the Six Day War, however many of the frameworks that were established continued to function, and certain collaborations on different levels even continued.For example Kenya, where the Nahal operated, and which was the beginning of the political relationship with it, which finally led to some cooperation during "Operation Jonathan" to free Entebbe hostages.
