In the vast universe, the nations in the universe are at war again. As a member of the Space Army Reserve, you need to do the necessary exercises! You will practice and graduate here. Remember, it is not easy. You have to concentrate and stay passionate. Now you have a brand new device. Remember that 20 years ago, we could only practice on simple tables, but today’s technology has rebuilt this one, and I believe your level will be further improved. Good luck, soldier.
