WW2 American Infantry Experience in European Theatre of Operations (ETO) - Audible Book: Closing With The Enemy

I can highly recommend my current Audible book on the US Army in the ETO (European Theatre of Operations) and how they fought .. or .. rather how they changed the way they fought from the Normandy beaches, through the bocage through France and into Germany. Incredible detail, particularly with reference to the urban combat (Brest and Aachen) and the ingenuity employed (see below, another book I pick away at during car journeys and walking the dog): 

Particularly as it gives great reference to US learning experience and their adaptation in confronting challenges - on the fly changes and inventing doctrine that worked (like pulling a M12 155mm SP howitzer into a street fight to emphasise a point to some defending Germans and positioning artillery perpendicular [aka already flanking the position to be attacked] to teh axis of attack on a village, so that there is no longer a problem of short rounds [blue-on-blue] and the attacking infantry can "pounce" on still stunned defenders).
