For example, you participate some activity where you see other people wearing some special equipment, and you don't feel like wearing that much. You asked if it is necessary to equip that. (Not something likely to happen but it's the most practical thing I can think of.)
Sorry my friend , i understand your explanation. but the sentence is still bad. Simply it is not natural english . correct way: do i need to be equipped .. Though it still sounds awkward however that is correct..at least.
From the explanation above, it sounds like that is what it means, it just doesn't translate literally into English in a way that doesn't sound dreadful.
That was the answer I gave, but it didn't accept it, and I agree this sentence just really doesn't translate well
this is not a complete sentence (question) in English. It needs to be followed by either a noun or a pronoun. Do I need to equip them? Do I need to equip the team? Do I need to equip Sarah to climb Mt. Everest? Do I need to equip Dr. Trang to perform surgery?
'Equip' is a transitive verb in English and requires an object. "Do I need to equip", is therefore an incomplete sentence. The complete sentence is, "Do I need to equip myself".
