PACK-DRILL – My favourite reference book Brewer’s Dictionary of Phrase and Fable tells us about the expression ‘No names, no pack drill’ alluding to military punishment. Offenders may be sent on a forced march in full kit (pack). But if the drill sergeant does not have the names of the miscreants, he is unable to impose this punishment on them, so the ‘anon’ will pass by without having to take part in exercise (drill’ in full uniform carrying a heavy pack.
