I would say more along the lines of a Guide dog Cuddles, as being a Gunner he probably couldnt find his own arris with both hands and a team of OCdts from Sandhurst and will be all over the feckin place as usual, without a Sapper to keep him on the straight and narrow
Yes, a Sapper will be ideal to carry the chief soldier's bags. Did I mention he is a gunner? Oh sorry, CGS is a gunner and a donkey-walloper to boot...
Lieutenant-General Peter Wall is a good choice (aside from being of God's own Corps). He performed well on TELIC (IMHO) and having briefed and been briefed by him, he is very much the pragmatist, and most definitely sees his Corps experience as fundamental in his approach. Very task orientated, but also shrewd enough to not only reflect on what is going on, he really does have the granite to drive stuff through.
