The Iron Curtain was the defensive line of Rangers F.C. during the late 1940s and early 1950s. The normal line-up in the early 1950s consisted of goalkeeper Bobby Brown, full backs George Young and Jock Shaw, centre half Willie Woodburn and wing halves Ian McColl and Sammy Cox. These positions refer to the old 3-2-5 formation, where the three defenders would mark the two opposing wingers and centre forward, while the wing-halves dealt with the opposing inside forwards. These direct match-ups meant that Rangers' Iron Curtain had several great confrontations with Hibs' Famous Five forward line of Gordon Smith, Bobby Johnstone, Lawrie Reilly, Eddie Turnbull and Willie Ormond.
