I wouldn’t call it “using” I would call it “supporting” since most of us fight willingly. There is no way any army could hold back Russia for 5 years if we weren’t extremely determined and willing to fight.
As for the fact that the West could've sent troops but chose not to, yes, that does hurt a lot of Ukrainians, and some do feel used. But we'll fight and win anyway, to defend our homeland, because we have no choice - material support from the West is better than nothing.
