Defence preparedness - Why do we make so much noise?

Looking at the alarms being raised by media about the chinese aggression on the northern border and Indian armed forces responding to it by deploying in the forward posts, my first thought is that we are unnecessarily creating the noise which will do no good other than alarming your enemy.

Its strange that governor of Arunachal Pradesh has given a public statement about raising a mountain division. By letting out such strategic decissions, we are loosing an edge that we may other wise. When you are telling loud about your forces, you are in a way loosing the advantage of giving the enemy an element of surprise. Afterall it was said that, Know your enemy and half the battle is won. I never saw any other country telling out loud about their operational deployments in the media. They are better kept as secrets.
