Some reports indicate that Russia's troops in Crimea were already scheduled for a new rotation about now, which would help explain the activity, though it would be quite a coincidence that this just happened to fall during some of the highest tensions since the 2014 annexation.
一些报道显示，俄罗斯驻克里米亚的军队早已计划好在现阶段进行一次新的轮换，这有助于解释有关活动，尽管很巧合的是这刚好发生在自2014年侵吞事件以来局势最紧张的时期。
