"Attack his foot!"

Translation: Serang kakinya!

[boringtomi]

When do you have to add "lah" and when you don't?. Would "Seranglah kakinya" work?

Why serangan kakinya is marked as incorrect?

[Rick392366]

'serang' is the base word, and it's a verb (to attack).
'serangan' is a noun (the attack).

[base word] + ['-an' suffix] = noun.

I'm worried about the guy with the foot.

Attack of the foot soldiers.
