lionnoisy SG GCHQ Challenge in Code Breaking I can assure u that it is a damn fun code breaking.There are few trials out. If u can break some ,why not contact The 1st Battalion, Military Intelligence (1 MI Bn) of Singapore,of course. The motto, 'First In', is a constant reminder to the battalion of its mission to provide timely and accurate information and the desire to be a cut above the rest. The nation need you!!
