The AT-4’s known operators include Argentina, Bosnia and Herzegovina, Brazil, Chile, Colombia, Croatia, Denmark, Estonia, France, Greece, Indonesia, Iraq, Ireland, Latvia, Lebanon, Lithuania, Malaysia, the Netherlands, the Philippines, Poland, Sweden, Taiwan, the UK, the US and Venezuela. This also includes the M136 variant, as publications are relatively vague on which nations operate which (although the M136, specifically, is used by the US, and not the AT-4).
