Signing up for the military
You have to be an american citizen and a high school graduate. the age limits are 17-39(though at west point it is 17-22). Another thing you need is an above average S.A.T or A.C.T score. you also can't have a criminal record.
If you have all of the requirements for signing up then good job but your not done yet! Before you can even start training at a military academy or base you have to pass a lot of fitness requirements. Each branch of the military has their own requirements so I will show you them.
ARMY:timed 2 mile run,2 minutes sit ups,and 2 minutes push ups
NAVY:timed 1.5 mile run or 500 meter swim,pull ups,2 minutes curl ups,2 minutes push ups,and sit and reach flexibility test.
AIR FORCE:timed 1.5 mile run, 1 minute push ups,1 minute curl ups
MARINES:timed three mile run,2 minutes pull ups,crunches
COAST GUARD:timed 1.5 mile run,1 minute push ups,1 minute sit ups sit and reach,5 minute water tread
If you can do that too than great but if it seems hard to you than I'd stop reading this article and go to a gym.The actual training is much harder than this and also includes marksmanship (shooting),paratroopering,hard physical work,hard intellengence work,and very minimal sleep.

Another problem has been terrorist attacks at large events especially the attacks at a concert in France last November.To help prevent something like that from happening in the future countries should have better security at big events and better trained police
