Answer:
I am black white and read all over.
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 am orange and sound like a parrot.
When you buy me I am costly, but the only use I have is hanging only. What am I?
I am born in fear raised in truth and I come to my own in deed. When comes a time that I'm called forth I come to serve the cause of need.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
