What slogan should be used to express condolences to the troops who are training?

Bleeding, sweating, no tears. Lose the skin, lose the meat, and don’t fall behind. Keep close to actual combat and highlight confrontation. Adhere to difficulties and be strict, and science and technology promote training. ...Use me in the first battle! Use me and you will win!!. There is no task that cannot be completed, no difficulty that cannot be overcome, and nothing that cannot be defeated...

I believe in you!
