Traffic on the single bridge that links Russia to Moscow-annexed Crimea and serves as a key supply route for the Kremlin’s forces in the war with Ukraine came to a standstill on Monday after one of its sections was blown up, killing a couple and wounding their daughter.
The RBC Ukraine news agency reported that explosions were heard on the bridge, with Russian military bloggers reporting two strikes.
RBC Ukraine and another Ukrainian news outlet Ukrainska Pravda said the attack was planned jointly by the Security Service of Ukraine (SBU) and the Ukrainian navy, and involved sea drones.

Wrong the rail line is the means by which military support is moved, Russia has a history of utilizing rail as their supply lines.
“The reason Russia is unique in having railroad brigades is that logistically, Russian forces are tied to railroad from factory to army depot and to combined arms army and, where possible, to the division/brigade level. No other European nation uses railroads to the extent that the Russian army does.”
“Trying to resupply the Russian army beyond the Russian gauge rail network would force them to rely mostly on their truck force until railroad troops could reconfigure/repair the railroad or build a new one. Russia’s truck logistic support, which would be crucial in an invasion of Eastern Europe, is limited by the number of trucks and range of operations.”

“Russia has to defend in 360°. It is heavily dependent on barge and rail movement. It does not have the manpower of Soviet times. It cannot be strong everywhere at once and has gone to highly mobile brigades so that it can rapidly assemble forces where needed.”
“The vast majority of personnel and cargo are transported via rail for civil and military purposes. Rail transport is the primary means of logistical support for most military operations (including current operations in and around Eastern Ukraine) and is an absolute necessity for any type of large-scale movement throughout the great expanse that is the Russian Federation”
“Due to the importance of rail for military operations, the Russian Federation has a separate branch, the Railroad Troops, dedicated to protecting, servicing, and maintaining rail service in combat and austere conditions for the Russian Armed Forces.”
