Thief

Flag:	Thief
File(s):	Rules(md).ini
Values:	Booleans
Default:	no
Applicable to:	InfantryTypes

In Red Alert, the Thief was an infantry unit that could enter a Refinery or Silo and steal 50% of the credits it contains.

In Tiberian Sun and Firestorm

The Thief flag was introduced in Tiberian Sun, and as its name and rules.ini description suggests, it was supposed to make the unit able to steal credits just like the Thief in Red Alert. Unfortunately, the flag does nothing at all.

In Red Alert 2 and Yuri's Revenge

Thief=yes allows the unit to enter a refinery but it does not steal any money (that is now achieved using Agent=yes).

Thief=yes is also required for VehicleThief=yes to work correctly.

Bugs/Side-Effects/Unexpected Limitations In Yuri's Revenge at least, if Thief=yes is set on an InfantryType then that InfantryType will be unable to enter guard mode. For example, setting Thief=yes on an Attack Dog will prevent the Attack Dog from detecting and attacking disguised enemy units automatically.
