I'm after the full quotation of a Roman Soldier ranting about training and reorganisation?

Quite a famous quote on many office walls of military personnel - In effect ';We trained hard and just as we started to produce we reorganised!!'; - still very relevant todayI'm after the full quotation of a Roman Soldier ranting about training and reorganisation?
';We trained very hard, but it seemed that every time we were beginning to form up into teams we would be reorganized. I was to learn later in life that we tend to meet any new situation by reorganizing--it can be a wonderful method of creating the illusion of progress while creating confusion, inefficiency and demoralisation.';





Attributed to Caius Petronius, but see link for interesting discussion on its origins.I'm after the full quotation of a Roman Soldier ranting about training and reorganisation?
Vegetius is the best known Roman Military commentator. He wrote in the 4th Century AD and many of his maxims are still relevant today.
It doesn't sound very Roman to me!
