在斯洛维扬斯克和克拉马托尔斯克附近的山脊上，乌军修建了宽约200米的多层防线：铁丝网带、两道或三道反坦克壕（约2米深、3米宽）与土堤反复交替，并在部分地段加入“龙牙”混凝土障碍和地雷。配合持续的无人机巡逻，这种分层结构旨在显著提高俄军突破的难度。
但谈判条款可能让这些工程付诸东流：俄罗斯要求在任何协议中获得其尚未征服的顿涅茨克约30%地区，而一份12月流传的方案称美国同意该让步并设想将该地区变为“中立的非军事缓冲区”，还提到未被定义的“自由经济区”。许多乌克兰人将其视为绕开防线的手段；与此同时，近几个月乌军持续失地，波克罗夫斯克大部已失守，科斯坚季尼夫卡面临威胁，随后可能轮到德鲁日基夫卡以及更大的克拉马托尔斯克与斯洛维扬斯克，尽管乌军在12月曾以高代价夺回库皮扬斯克部分地区。
该地区在冲突中的立场也在变化：2014年克拉马托尔斯克和斯洛维扬斯克被亲俄武装占领，乌军用将近三个月才将其逐出，部分亲俄者逃离而另一些人留下并转变看法。民间组织警告，若要把地区改造成缓冲或经济区，不能“把数十亿美元砸下去”就指望其正常发展；当局甚至停止向居民发送撤离热线，而最近俄军阵地距此仅17公里，短程无人机袭击更频繁，一些居民已开始离开，仍有人因缺乏选择而被迫留下。
Near Sloviansk and Kramatorsk, Ukrainian forces built layered defenses about 200 m wide, repeating belts of wire and two or three anti-tank ditches roughly 2 m deep and 3 m wide with berms, and in places adding concrete “dragon’s teeth” and mines. With constant drone patrols, the depth and repetition are meant to make a Russian breach far more difficult.
Negotiations could still nullify these works: Russia wants any deal to grant it the roughly 30% of Donetsk it has not conquered, and a proposal circulated in December said America would accept that while turning the region into a “neutral demilitarised buffer zone,” also invoking an undefined “free economic zone.” Many Ukrainians see this as a way to bypass defenses as Ukraine has lost ground in recent months—most of Pokrovsk has fallen, Kostiantynivka is threatened, and then Druzhkivka plus larger Kramatorsk and Sloviansk could follow—even though Ukrainian forces pushed Russians out of part of Kupiansk in December at high cost.
Local alignments have also shifted: in 2014 Russian-backed rebels seized Kramatorsk and Sloviansk, and it took Ukrainian forces almost three months to eject them, after which some pro-Russian supporters fled while others stayed and later changed their minds. An NGO warns that creating any buffer or economic zone cannot be done by “dumping billions of dollars,” yet evacuation guidance has reportedly been reduced as the nearest Russian positions sit only 17 km away, short-range drone attacks have grown more common, and departures are beginning even as some residents feel they have no alternative but to remain.
