The security agreement says some of those troops could work at the tactical level, meaning they could go out on operations.

这份安全协议表示，这些士兵中有部分人将在战术层面上工作，这意味着他们可能会参与到行动中去。

I think there's a lot more talk going on at the tactical and operational level, while the heads of state remain bellicose but it is just upping the ante and you never know when this might happen.

我认为在战术和投入使用层面会有更多对话, 而俄罗斯领导人依旧还是好战派，但这样的系统只是加大赌注筹码, 你永远不知道什么时候才能发生。
