[Vanilla Bug] Unit mission "Ambush" does not work

[Crimsonum]

First Check

• I added a very descriptive title to this issue.
• I used the GitHub search to find a similar issue and didn't find it.
• I have attached as much information as possible (screenshots, debug and exception logs, etc).

Description

There is a unit mission called Ambush which does nothing useful. A unit set to this mode will lie motionless and unresponsive until attacked, after which it will pursue the attacker.

According to TD and RA source code, an AI unit set to this mission should hunt down enemies when it's discovered. However, there's a typo in the code which prevents this from working. It's likely TS has the same issue.

Required Code (optional)

Steps To Reproduce

Actual Behaviour

The AI unit remains motionless and unresponsive.
