The sentence is Imperative if it requires or forbids some action from the listener.
Imperative mood (abbreviated as IMP) is the grammatical mood that is used to indicate commands, requests and strict prohibitions. Imperative is the default, dictionary form of verbs in Black Speech. None of the inflectional suffixes and none clitic subjective pronouns (prefixed) can be added to it to express imperative mood, however objective pronouns can join verb.
In the narrow sense Imperative mood applies only to direct orders to 2nd person (implying “you”), but it's grammatical form is also used in other modalities expressing orders. If subject pronoun (usually “you”) is required then it should be put in Dative case, thus the sentence becomes impersonal.
