 Several modern historians have also praised the operation and the improvements that were made for Varsity . G. G. Norton argued that the operation benefited from the lessons learned from previous operations , and Brian Jewell agrees , arguing that the lessons of Market Garden had been learned as the airborne forces were concentrated and quickly dropped , giving the defenders little time to recover . Norton also argues that improvements were made for supporting the airborne troops ; he notes that a large number of artillery pieces were available to cover the landings and that observers were dropped with the airborne forces , thus augmenting the firepower and flexibility of the airborne troops . He also highlights the development of a technique that allowed entire brigades to be landed in tactical groups , giving them greater flexibility . Dropping the airborne forces after the ground forces had breached the Rhine also ensured that the airborne troops would not have to fight for long before being relieved , a major improvement on the manner in which the previous large @-@ scale airborne operation , Market Garden , had been conducted .
