Wife is not so excited because she swears he is coming home in a bag from Iraq. I am proud that he made another good decision for himself. He graduated High School, he is an Eagle Scout, and he returned from his mission for the Church of Jesus Christ of Latter-Day Saints (Mormons) in March. Now he is on to serve his country! So, that being said - what does a 21 year-old young man need to know and do to be the best Marine available? He is drilling with the delayed entry group and doing calesthenics at home. I have taught him how to shoot Glock, rem 870 and .22s. I am thinking about getting a Beretta 92FS and an AR-15 for him to practice with as well. His entry date will be August something so he has a few months. What do you more experienced leathernecks think he should do to prepare?
