Commonwealth grave headstones follow a set layout; a decision was taken at a very early stage that all of the fallen should be treated equally, whether they were officer or other ranks.

At the top is typically a regimental crest or badge - for example, Army Cyclist Corps, Royal Canadian Air Force or Royal Navy.
This is followed by the service number and rank of the deceased.
Then we see the initials, the family name follwed by the Regiment, date of death and age.
Below this may be a religious symbol such as a Christian cross or the Star of David.
Finally there may be a personal inscription chosen by the family.
