The corps ASM does not have an audio tape player inserted into his posterior. The original poster has got got confused. What really happens is when a tiffy student arrives at Bordon or Arborfield for his course in addition to the spine being removed, their brain is removed and a tape player fitted in its place. This allows the tiffy to then insert the correct tape for the required occasion. For example the latest DEME A directive for when he next visits. However what with advances in technology there is now an immediate mod being prepared to facilitate the removal of the tape unit and replace it with a DVD drive to allow more info to be stored and faster access to relevant files.
