Combat A.I. protocols: "if able" interpretation

[Rodraggor]

B1 Battle Droids - Combat A.I. protocols
"After an allied BATTLE DROID Unit makes a combat action, choose one of the targeted characters that is within 4 of all characters in this Unit, if able. The chosen character gains X or Y."

Why the term "if able"?

- Some people think this means that a targeted character must be within range 4 of both B1 characters (= if possible), but that otherwise, a character within range 4 of a single B1 character is sufficient.
- Other people, including me, think this means you need a targeted character within range 4 of the 2 B1 characters (= if possible), otherwise nothing happens.

What's the correct interpretation?

This is correct.

If the targeted character is not within range 4 of all characters in the B1 Battle Droids Unit, you will not be able to apply one of the listed conditions to them.
