asked the Minister of Supply to what extent it is the practice of Government scientists and other technicians engaged on the design and development of military equipment to spend part of their time in the field observing the use of this equipment under working conditions.

Scientists and other technicians engaged on the design and development of military equipment observe the performance of the equipment under working conditions particularly at prototype trials conducted by the Services. They also frequently visit units and formations using the equipment after it has been put into Service use.
