Target number
River and Sea (Non-IEC system): An acquired target gets the youngest unused
number. When a target is lost and disappears from the number list, the next acquired
target takes the number of that lost target (for example, In a 5 target list, if the target
2 is lost, the next acquired target takes the number of target 2).
IEC and Russian-River (IEC system): An acquired target gets the youngest unused
number. When a target is lost and disappears from the number list, the next acquired
target takes the next sequential number until reaching a maximum 10. If the target
number reaches a maximum 10, the next acquired target takes the number of a pre-
viously lost target.
