yes but
If your enemys soldiers are scared by shiny metal then they are not much of an enemy. Get our guys to shoot so well(USMC) the enemy wont stand a chans in an infantry firefight. that should scare the enemy....Make sure your tank gunners are not only capable of hitting 1st round from 6000ft, but also open fire and hit with the 2nd or 3rd from 15000(Israeli Armored Core), so your enemy tank commanders fear encounters. thats good intimidation, not a knife, or triangular metal attached to your gun.....
