From the Colonel's Regiment
The experience was a concept introduced for Mission 2 2 Dublin. It refers to the first meeting between two or more Colonel's men about to go on a mission. Should they be meeting up with the purpose of going on a mission (and not going their separate ways before the break) then it is said that their Colonel's break experience has started. The first "experience" to be enjoyed by the Colonel's men was between Rupert and Mike, when they met up on the cycle bridge in Cambridge just prior to Mission 2 2 Dublin. David joined an hour or so later to begin his Colonel's break experience. When two or more groups of Colonel's men meet up whilst having their own Colonel's break experiences, the result is a Grand Unified Experience or (more rarely) an Experience of Everything.
