上帝啊，看来今天晚上我睡不成了，我刚刚听到持续的警报声，我们正奉命进入基地要塞，因为有一些迫击炮弹来袭。

Oh my God, looks like I won't be sleeping tonight as well, as I just heard the siren go on, and we are being instructed to go into the fortified bases because there are some mortars coming our way.

你能模拟演示一下吗？我要听到警报声。

Can you demonstrate it by imitating? I want to sound alarm.
