There actually is Mototolv rules already in the book. However, I question, the Sniper can really cause Demorlaization, but can it be used for removing a mechwarrior from a cockpit, closed canopy? Other then the obvious "if it works for you"
Thanks to A Time of War, the BAR of battlemech cockpit glass is known. It takes a sniper using a Radium Sniper Rifle
a Margin of Success of 4 to breach the BAR of the cockpit glass and hit the pilot. Now, if we are talking about
a professional sniper, the first shot should be followed immediately by a second shot going through the hole he
just made in the window(this still requires the same number, IIRC, due to the called shot penalty, however
on this shot, the round should go through the 'mechwarriors cooling vest, since the BAR of the cockpit is not
being added to the armour).
