Its is important because it helps prevent lots of damage when there are wars and to also honor the people that serve to help protect our country. These people called Veterans have served for us for a good reason and that reason is to keep us safe from any danger that may happen. Serving on a Jury is important, You shouldn't take it for granted because its a blessing and a giving to protect the U. S. A. from anything that comes at them. The United States may not seem it has done anything but from what we don't know is they they do everything they can to help us, that's why they have presidents to take action, to warn people from any danger that could harm us. It benefits our community from being thankful for what these Veterans do. It also benefits our community by keeping it secure, by profit, well-fare, assistance, serving or serve, comfort, help, and also by a blessing.
Hope that helps :)
