Yes.
My grandmother, who was the wife of a World War One soldier, told me that Anzac biscuits became popular for wives and mothers to send to the troops because they kept well, travelled well and tasted good.
Fruit cake was another very popular food item to send. When alcohol such as brandy or rum was added the cake not only keeps really well, but was also a big hit with the troops.
Which would you prefer?
Army issue - The army biscuit, also known as an ANZAC wafer or ANZAC tile, is essentially a long shelf-life, hard tack biscuit, eaten as a substitute for bread. Unlike bread, though, the biscuits are very, very hard. Some soldiers preferred to grind them up and eat as porridge.
Home made ANZAC biscuit - The popular ANZAC biscuit is a traditional, eggless sweet biscuit made with golden syrup or treacle.
Recipes for both available from the Australian War Memorial site.
