An interesting topic on the Bandoliers worn by men of the Royal Artillery. Many photographs of individuals or batteries can be seen with this item of equipment being worn - great question from Tyrim - where are the rifles ?

It transpires there were 36 rifles allocated to a battery, so they were not personal weapons (100 plus in a Battery), and as the can be allocated to anyone, everyone carried ammunition.

So 5 pouches .... 2 for ammo (10 rounds), 1 for cigarettes, 1 for matches, 1 for choccy bar
