The form used for Royal Navy and Marines fitness reports is the S206. The following are actual excerpts taken from people's "206s"....

• His men would follow him anywhere, but only out of curiosity.
  
• I would not breed from this Officer.
  
• This Officer is really not so much of a has-been, but more of a definitely won't-be.
  
• When she opens her mouth, it seems that this is only to change whichever foot was previously in there.
  
• He has carried out each and every one of his duties to his entire satisfaction.
  
• He would be out of his depth in a car park puddle.
  
• Technically sound, but socially impossible.
  
• This Officer reminds me very much of a gyroscope - always spinning around at a frantic pace, but not really going anywhere.
  
• This young lady has delusions of adequacy.
  
• When he joined my ship, this Officer was something of a granny; since then he has aged considerably.
  
• Since my last report he has reached rock bottom, and has started to dig.
  
• She sets low personal standards and then consistently fails to achieve them.
  
• He has the wisdom of youth, and the energy of old age.
  
• This Officer should go far - and the sooner he starts, the better.
  
• In my opinion this pilot should not be authorized to fly below 250 feet.
  
• This man is depriving a village somewhere of an idiot.
  
• The only ship I would recommend this man for is citizenship.
  
• Works well when under constant supervision and cornered like a rat in a trap.
