Joining the service is not the opportunity it used to be as the services have become very picky as to who they will accept.
One reason is that more than 70% of young Americans in the prime armed forces recruiting cohort (18-25 year olds) no longer qualify for military service, due to such factors as past criminal records, obesity and excessive recreational drug usage. Many of the young snowflakes are also unable to achieve a qualifying score on the ASVAB, a product of our failed government schools.
Finding enough recruits to expand the U.S. military under President Trump may be more difficult than many would believe.
