It depends.
Army and Military personnel are those who are not afraid to give their life and their family/love for their Nation. They are willing to die and/or bear pains/tortures just to see their citizen happy and free of all tensions. I, for myself, consider the elders of my nation as parents, the peers as friends, and the youth as my children. I won't mind dying if anything comes towards them. My nation is my family.
But, being a senior officer after ranks of Major comes with threats not only in war zone but to your direct family's life. Blackmailing to do/not do something and forcing you. That is more dangerous. Choosing between direct family and nation. If your friend (which I think is no one else but you yourself asking the question) is not brave enough to tolerate this, I recommend not joining the forces. Anyways the training is too brutal resulting in many cadets running away from PMA. No wonder we are classified as top class warriors in the world and our Air Force as best in training and Intelligence as best in operating.
