What’s old is new again as Russia’s wider war on Ukraine grinds toward its fourth year. During World War II, some armies—the British Army, in particular—bolted metal spans to the top of tank chassis and used the resulting “funnies” to rapidly erect bridges across vehicle-halting gaps on the battlefield.

The 67th Separate Mechanized Brigade repelled an assault of Russian troops near the village of Zhuravka in Sumy Oblast on the border with Russia's Kursk Oblast, according to the brigade's Jan. 15 statement.

Russian forces allegedly targeted a nursing home facility in the Ukrainian-controlled territory of the Kursk region.

Ukraine’s continued focus on Kursk shows how important Kyiv believes it is to hold on to Russian land, especially if Trump pushes both sides to the negotiating table.

Ukrainian President Volodymyr Zelenskyy said that some 38,000 Russian troops have been killed or wounded fighting in Russia's western Kursk region since August.

Russia said on Monday its forces had made important gains in eastern Ukraine while continuing to fend off a new Ukrainian offensive inside the Kursk region of western Russia, where a second day of fierce fighting was under way.

Ukraine's fresh offensive in Kursk comes nearly six months after Kyiv first sent troops into the western Russian region.

A Ukrainian mopping-up group encountered one surviving North Korean fighter who had set an unsuccessful trap. The soldier attempted to mislead the Ukrainian soldiers and then detonated a grenade to avoid capture,

Ukraine aimed to challenge the self-imposed red lines set by the Biden administration and other Western leaders regarding its ability to strike back against Russia.

The NIS attributed the high casualties to the soldiers' "lack of understanding of modern warfare," including their "useless" attempts to shoot down long-range drones.

Ukraine launched a daring offensive into Russia's Kursk region, hoping to stretch Russia's resources and gain a new bargaining chip.
