Aliases: [ High payoff target types, High payoff type of targets, High payoff types of targets ]
A collection of collections, each instance COL of
high payoff target type is a collection of objects
that by default will be a target by opposing
forces during or in preparation for a battle.
In other words, we assume
that a threat to a particular military force
will target with artillery, reconnaissance, or other
of their unit-types, when feasible, instances of COL
unless we have information to the contrary.
