While you don't need a lot of property to keep emu -- they are ideal for farms consisting of 10 acres or less -- you do have to install strong, high fencing to keep them confined. For best results, put up a fence at least 6 feet high. At minimum, you need a 5-foot fence, but some emus can jump over that.
Across the United States Armed Forces, the maximum age for enlistment for someone who has never served in the military before depends on the branch. For the Army, the maximum age is 35. For the Navy, age waivers start at 34-years-old. For the Air Force, the maximum age allowed to join is 39-years-old. The Marines have the lowest maximum age for regular military service at 28-years-old.
Question: What is the maximum age to become an officer in the Military? Answer: By law, the maximum age for a commission is age 35. This is because a military officer must be able to have 20 years of service, to be retirement eligible by the maximum retirement age of 55. There are a few exceptions: Military medical officers and chaplains can be commissioned up to the age of 47 with waivers into their 50s (they also don't have to retire by age 55). Depending upon the need for doctors, psychologists, chaplains (all faiths), and legal officers as well, the maximum age can be waived.
