America is a country where it's legal to buy and own guns.
Although the strictness of gun control varies from state to state, you could always get your hands on an automatic rifle when you wanted one.
Cheng Daqi and his companions heard gunfire, which was the sound of an AR15 automatic rifle being fired.
Scott could even determine the specific type of bullet from the sound.
He had returned from Afghanistan, where, before going back to America, he had spent eight years in that terrifying mountainous region.
For eight years, those enemies, some barefoot or wearing sandals, had seen their equipment evolve from workshop-made AKs to AR15s, from improvised land mines and cannon to modern weaponry identical to that of the American troops.
As for who wanted to continue fighting that damn war, Scott was genuinely tired of it.
When he first left, Scott thought he was in great shape.
Far from the war, he had returned to his peaceful hometown.
