QuarryTypes

There are various target types that teams and special weapons can be assigned to attack. These are general target categories since the actual disposition of potential targets cannot be precisely predicted -- thus these serve as guidelines for the computer AI.
—Red Alert source

Quarry¹ types is a feature first introduced in Red Alert. As explained by the above comment in the game's source code, they are used to specify general target categories for AI teams and special weapons (super weapons in later games).

Usage

Quarry types are used as a parameter in at least two places:

• Team mission type 0 to specify the quarry for the team
• Trigger action type 35 for special/super weapon targeting
