对于一名战士,一枝性能优异的步枪就是纵横沙场的利器。可是,假如你是一名海军陆战队的蛙人,准备潜水去完成作战任务,那你千万不能拿着步枪下水,因为步枪在水下发射时,只能把0.9米外的木板打出一个小坑。所以,在水下用步枪射击就像用拳头打人一样,威力太小。那怎么办呢?你只能拿着匕首和敌人展开水下肉搏。不过,后来有了新的变化。一、水下200米内,杀无赦! For a soldier, a performance rifle is vertical and horizontal weapon. However, if you are a Marines frogman, ready to dive to complete the combat mission, then you must not take the rifle into the water, because the rifle launch underwater, only 0.9 meters outside the board hit a small pit. So, shooting underwater with a rifle is like striking a fist, the power is too small. So what to do? You can only carry a dagger and enemies underwater combat. However, new changes came later. First, within 200 meters underwater, kill no amnesty!
