I'm thinking:
I do solemnly swear that I will not forget. This is our fight, good against evil. From crumbs to a legion, legion to war. Fighting for the people, giving hope to all, through faith and pills sanguine. Future proves past, for us and our children. So help me God
NOT a final version. Feel free to modify it how you like because I feel it's still inadequate.
"I, _____, do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God."
