I shall clarify this to you that - when you become a soldier, you lost yourself. It¡¦s not a good thing. It is because you just sell (or entrust) your precious soul to some human beings.
Forgive me being bitter, but I shall point out that you are a ready tool to harm. I¡¦ll explain further: You are not only selling yourself, but also, you agree assimilating the other free spirits via your superiors¡¦ orders. You sell out yourself and other innocents.
Do you want to hear what Jesus said before he was arrested by the authority? He said to Peter who was armed with a sword, saying ¡§Peter, put the sword down. Whoever lifts up a sword will perish with a sword.¡¨
Maybe you are Jewish. Do you know Old Testament well? The LORD God created this world to be vegetarian. So killing each other wasn¡¦t allowed. In fact, it is never allowed any time. If you want to ask me why God called up an army, I shall tell you it was for a show. Anyway, I am too much away from the topic now. So I leave you with one word here - to kill or make alive is God¡¦s business.
Army Creed is not army. It is the instructions in every aspect of civilian life. Be kind, be loyal etc are pretty much fulfilling everyday business. It¡¦s ordinary if you know what I mean. Wake up before sun rises, then repeating it loudly doesn¡¦t give you extra light over your head.
Greeting flag is a sin.
