The ISTAR Battalion (BISTAR, Batalhão ISTAR in Portuguese) is the Portuguese Army unit responsible for centralizing the intelligence, surveillance, target acquisition and reconnaissance (ISTAR) missions.

The ISTAR started to be raised in 2009, following NATO requisites and the need felt by the Portuguese Army to develop the capability to give ISTAR support to its operational brigades and to its deployed forces in foreign territory.^[1][2]
