Answer:
I march before armies a thousand salute me. My fall can bring victory but no one would shoot me. The wind is my lover one-legged am I. Name me and see me at home in the sky.
I think you live beneath a roof that is upheld by me; I think you seldom walk abroad but my fair form you see; I close you in on every side you very dwelling pave and probably I'll go with you At last into the grave.
I am good at concealing what's real and hide what's true. Sometimes I bring out the courage in you!
I turn everything around but I cannot move. When you see me you see you!
I'm not really more than holes tied to more holes; I'm strong as good steel, though not as stiff as a pole.
No matter how little or how much you use me, you change me every month.
