自亚努科维奇总统被罢免以来，乌克兰局势持续紧张。

He says the troops will also regularly organize combat readiness patrols to defend national sovereignty and territorial integrity.

他说，部队还将常态组织战备巡逻，捍卫国家主权和领土完整。

The move on Tuesday came a day after Serbia put its troops near the border on a high level of combat readiness.

此举发生在周二，即塞尔维亚军队进入最高级别战备状态，并被部署在边境附近的一天后。

The exercises focus on practicing joint maritime and aerial combat readiness patrols, joint seizure of comprehensive battlefield control, and joint precision strikes of key targets, Li said.

李说，演习重点演练海空联合战备巡逻、联合夺取战场综合控制权、联合精准打击重点目标等。

The drill designed to estimate regular combat readiness can be out of the question as it was conducted within the territorial waters of the DPRK according to a plan of KPA routine drills.

根据朝鲜人民军例行演习计划，此次演习是在朝鲜领海内进行的，目的不可能只评估常规战备状态的演习。
