Hi Phillip and George,The custom of the guard turning out was still in existence when I left the Bn in 68,it was customary for all soldiers to recognise all officers of the Bn,the Bn orderly officer was always in uniform and was most likely accompanied by the Bn orderly Sgt.visiting officers normally arrived by car and would be checked at the barrier,the guard commander was always informed beforehand of senior officers arrival,their car normally bore a 1star or more depending on rank,the Bn orderly officer turned out the guard at a time set by the adjutant,other times that the guard turned out was at first post(retreat) and the last post,the guard was always inspected at these turnouts.
Jankers,confined to barracks was a punishment for minor military offences(late on parade,dirty boots,unshaven etc)this punishment was awarded by the OC Company or commanding officer,first parade for these offenders was 15 mins after reveille with other parades throughout the day and evening,the last parade was at Last Post when they were inspected by the orderly officer,minor offences were recorded on the soldiers minor offence form and checked by the Bn 2i/c once weekly
