Cheek to jowl

"The Russians used the “cheek to jowl” tactic, closing to less than 50 meters of the Wehrmacht's front line, too close for the Germans to call in artillery or Stuka support. It forced close quarters combat that the Russians had trained to conduct and the Germans had not."

"These beach side developments continued for miles and—as we entered the city—were replaced by large hotels, sitting cheek to jowl, just across the highway from the beach which fronted on the gulf."
