you have seen that every country like USA, Germany, Mexico and so on have an army. why do they have a army what is the use of army? each country has a army so that it could potect the nation from the other countries and other invaders. if there will be no army in these countries then how will be nation will be protected by the other rival countries and invaders. and you make that a solider life is easy but it is wrong soldiers spend their time away from their families for ten years or many years so that you can live safely with your family. so never try to compare yourself with the soldier because you are a only a ordinary man and that solider is the country solider. so this is the importance of army. but there are many countries who don't have army support so we should only hope that something miracle will happen.
