To analyse in whole, Britain's WW2 military was far behind the Germans apart from a few key areas, radar, air force (RAF) and its German code breaker (Enigma). The Germans were far ahead in tank technology and with U-boat submarines. The Germans also had higher amounts of military personel at their disposal. Britain's success lay in the Battle of Britain where the combined use of radar and code breaking allowed the Royal Air Force (RAF) to beat the Luftwaffe, from then on the Luftwaffe were more or less depleted, contributing to German defeat.
