You don’t join a military, and then bitch and complain if you are sent to fight
Look at yourself, you are talking like an human without soul. People are not robots or machines they join the military because perhaps they believe in justice and want to defend their own people from villains. There's no justice in fighting a war for business, there's no justice in fighting wars for corrupted politicians at the expenses of innocent people.
We are all humans and everyone should be allowed and encouraged to talk not to keep his mouth shout.
