Former ruler Augusto Pinochet was implicated in the arms deal
Four retired Chilean army officers have been jailed for the 1992 murder of a colonel who had given evidence about an illegal arms deal with Croatia.
Two former generals, Victor Lizarraga and Carlos Krum, and two colonels got sentences ranging from two to eight years for their part in the killing.
A military court sentenced 11 others in June for their role in the arms deal.
A ban against sending arms to Croatia was in place during the break up of the former Yugoslavia in the early 1990s.
In December 1991, Hungarian police discovered a weapons shipment marked "humanitarian aid" allegedly approved by Gen Augusto Pinochet, who continued to head the army after his the end of military rule in 1990.
Col Gerardo Huber, who was in charge of buying weapons for the Chilean army, was found dead a year after he testified in a military investigation in 1991.
His death was ruled a suicide for 13 years before the case was reopened in a civilian court.
In addition to the two generals, Col Manuel Provis and Col Julio Munoz, both retired, were also jailed for conspiracy and murder.
