Question to the Ministry of Defence:

To ask His Majesty's Government what assessment they have made of the difficulties posed by soldiers in the same platoon using different calibre weapons and ammunition.

All procurement projects look at interoperability as part of the scoping requirements. The British Army currently operates different calibre weapons within the platoon; this provides a tactical advantage in ensuring the correct weapon is available to meet requirements, whilst also balancing other factors such as logistic and human considerations.
