Easy one this. The US has had two, six-star generals in its day. It is argued that it, the rank, was only used on ceremonial occasions The rank denotes 'General of the Armies' - as opposed to a mere 'General of the Army' -, and has no equivalent in the British or Commonwealth forces - and causes long looks from anyone used to seeing a (Click here - Field Marshal) (or Five Star General) as the highest ranking soldier at the table. No small irony that the US only awards a fifth star to generals now at a time of war (i.e. in extremis) and the rank of Field Marshal has been moth-balled and only used for Cenotaph duties. OK - and without using Google! - can you name the two US Generals in question?
