The Wide World of Mystery - 1973 Frankenstein Part 1 1-2 is rated/received certificates of: Australia:M
You had to be eighteen to join the military in both World Wars. There were foolish teens who gave false ages and did not present birth certificates to prove their age. So some fifteen years olds actually managed to get themselves enlisted. Some of them wrote home to ask their parents to go to the military recruiters office and present their birth certificates to get them out once they found out how hard boot camp and war was. Some parents let their sons suffer as punishment. Sadly some of them died in World War 1.
The countries that were the primary combatants of World War 1, started building their military long before the war started. These countries were rivals and if one country expand their military, then their rival would do the same. After some time these countries had large enough militaries of their own to start a war.
The bonus army, a collection of world war veterans and their families gathered in DC in 1932 in protest of the world war adjusted compensation act. This act delayed their promises payment until 1945. They were given certificates that would build compound interest until that date. However, this was during the great depression and the veterans needed their promises cash immediately, so they demanded it be cashed immediately. The gov refused, and Hoover ordered general Douglas MacArthur to drive them off all government property.
17, with parental consent. Many US states had only begun issuing birth certificates just a few years before WWI though, so most WWI soldiers did not have one. This made it more or less easy to fib about your age and enlist a little younger.
