Question: How many years were there between the re-forming of the 20 Battery Royal Artillery and the beginning of the Cuban missile crisis? Passage 1:June McCarroll (June 30, 1867 – March 30, 1954) is credited by the California Department of Transportation with the idea of delineating highways with a painted line to separate lanes of highway traffic, although this claim is disputed by the Federal Highway Administration and the Michigan Department of Transportation as two Michigan men painted centerlines before her. She was born in Lewis County, New York. She was a nurse (later a physician) with the Southern Pacific Railroad in the early 20th century. According to a historic marker in Indio, California, after a near-collision in her Model T in 1917, "She personally painted the first known stripe in California on Indio Boulevard, then part of U.S. Route 99, during 1917."
 Passage 2:Padukone's performances in her four releases of 2013 earned her various accolades. She was nominated for the Producers Guild Film Award for Best Actress in a Leading Role and won IIFA Jodi of the Year (along with Ranbir Kapoor) for the blockbuster romantic comedy Yeh Jawaani Hai Deewani (2013). She subsequently won Best Actress awards at the IIFA and Zee Cine awards and earned additional Filmfare Best Actress nomination for her performance of a Tamil girl on the run in the blockbuster romantic comedy Chennai Express (2013). She also received her first Filmfare Award for Best Actress for her role of a Gujarati girl based on William Shakespeare's Juliet character in the tragic romance Goliyon Ki Raasleela Ram-Leela (2013). Her performances in the satirical road comedy Finding Fanny (2014) and the heist comedy Happy New Year (2014) won the Star of the Year (Female) award at Stardust. The following year, she received various accolades for her role as a Bengali architect in the comedy-drama Piku, including her second Best Actress award at the Filmfare, Screen, Producers Guild and IIFA awards along with Zee Cine Best Actress Critics Award. Additionally, Padukone won Stardust Award for Best Actress for her performances in the former and the romantic drama Tamasha (2015). That same year, for her role as Mastani in the historical romance Bajirao Mastani (2015), she received additional Best Actress nominations from the Filmfare, IIFA, Producers Guild Awards and won Zee Cine Best Actress award.
 Passage 3:After the Second World War the Battery was re-formed in 1955 as 20 Medium Battery as part of 21 Med Regt based at Redford Barracks, Edinburgh but deployed in the Internal Security role to Cyprus in 1956 where the Regt lost several men to the EOKA terrorists. Re-numbered again and re-rolled (a change of equipment and role) as an Amphibious Operations (AO) Battery. They were posted to Hong Kong and renamed 20 Commando (AO) Battery as part of 29 Commando Regiment. Due to the fact that only 20 and 148 Commando (AO) Battery fulfilled the AO roll there was a lot of movement between the batteries most men serving in both. The battery had absorbed 3 (AO) Troop on their move to Hong Kong and was involved in a number of operations including the Korean War and a little known operation in the Caribbean during the Cuban missile crisis. The Battery was involved in clearing Russian, American and Cuban personnel off remote Caribbean islands in the region and arrested 60 men who later turned out to be CIA operatives, causing a minor political incident. The Battery was placed into suspended animation in 1969 following the downsizing of the British Army and the reduction to one Commando Artillery Regiment, having lost out to 148 Commando (AO) Battery. Many of 20 Commando (AO) Battery's personnel ended up in 148 Battery and so did much of the battery property.
