Why doesn't the Abrams use slat armour? So I've been wondering about this for a while but why doesn't the Abrams use slat armour? I understand it already has the option for the reactive armour package but I've seen a mix of reactive and slat armour on other tanks such as the Leopard that was used by the Danish and Canadians in Afghanistan. So how come the Abrams doesn't go for this mix?
