The cessation of all US aid to Ukraine also means the end of US restrictions on Ukrainian strategy.
Targets that apparently were forbidden can now be attacked.
The vulnerable electrical system that powers the trains that supply everything to the Russian army lead that list. 1/
The Russian army is supplied by railheads as close as possible to the front.
Russian mainline locomotives run on electricity, with an associated system of electrical substations and transformers that are exceptionally vulnerable to disruption. 2/
Russian attacks on Ukrainian electric infrastructure has shown that repair and replacement of transformers is very difficult, and Soviet designed transformers are unique to Russia.
And Russia’s limited truck fleet could replace only a negligible percentage of rail capacity. 3/

The mineral deal that President Zelensky will sign in Washington is very different from the first US demands, and in fact will strengthen Ukraine.
A report from European Pravda outlines the dramatic negotiations between US and Ukraine in the unprecedented time of just 2 weeks. 1/
On February 12, US Treasury Secretary Scott Bessent handed Zelensky a draft “partnership agreement”.
It apparently demanded ownership of 50% of Ukraines rare earth deposits as repayment for “US aid debt ”, apparently angering Zelensky as he was pressured to sign immediately. 2/
But Ukraine believed that engaging Trump in his preferred transactional style could work to their benefit.
After all, the mineral deposits were in the occupied East and would need to be repatriated.
The main thing was to find the offer that would interest the President. 3/
The flight controller (FC) of an FPV is the brain of the drone, coordinating motor control and sensor data to keep the drone stable and responsive.
It takes data from the pilot (via the radio receiver) and onboard sensors, then adjusts the drone’s behavior in real-time. 1/
The FC processes signals from the pilot’s transmitter commands, like throttle, pitch, roll, and yaw.
These come through a receiver connected to the controller.
The FC interprets these inputs and translates them into specific motor speeds. 2/
For example, if you push the throttle, it tells all the motors to spin faster, lifting the drone.
Tilt the stick to roll right, and it’ll increase speed on the left motors while slowing the right ones, tipping the drone accordingly. 3/
A Russian blogger comments on the scarcity of Russian heavy drones.
“On this day, we will publish a video of the successful work of the crew of a heavy attack drone (aka agro-drone "vampire", "baba-yaga", etc.) of one of the units with which we work… 1/
“…closely on the project to restore enemy heavy UAVs.
This agro-drone was assembled in our PriZhrannaya UAV-workshop, we made some of the drone parts ourselves, even improved something, … 2/
Russian heavy aerial bombs with precision-guided glide kits are causing great damage and many Ukrainian dead.
The UMPK glide kits allow Russian aircraft to launch 500kg, 1500kg or 3000kg bombs 30-90km from the frontline, out of reach of Ukrainian air defense systems. 1/
Russian air defense systems have taken heavy losses, but are strong enough to prevent Ukrainian aircraft from interfering, and so far this includes the new F-16s from which much was expected. 2/
The accuracy of the UMPK is centered on the “Cometa-M” satellite navigation system, a CRPA device that has proven very resistant to extensive Ukrainian GPS/GLONASS EW jamming.
This is the same system that guides the Shahed-136 kamikaze UAV. 3/
Russian blogger “Philologist” continues his candid analysis of Ukraine’s drone domination near Pokrovskii.
Ukraine’s system of separate drone battalions and now brigades allows vital concentration in critical areas. 1/
“In the current situation with the Pokrovsk direction, it is quite obvious that the combination of aerial reconnaissance of the lower skies with strike drones and artillery with an optimized organizational structure and a flexible system of control of fire and strike assets… 2/
“…allows the enemy to very effectively suppress the logistics of our troops.
The vulnerability of logistics is a general problem, the Pokrovsk direction here is simply a vivid illustrative example.

Russian blogger “Philologist” provides a vivid description of overwhelming Ukrainian strength in drones near Pokrovsky.
“‼️ Information from the ground on the situation in the southern section of the Pokrovsky direction. 1/
“We have no strength, we don't know what else to do. The sky is completely behind the [Ukrainians]. You can't go further than 3 km from Selidovo, they burn everything to hell.

There are a lot of comedians on optics, they monitor all the dirt roads 24/7. It's simply impossible to carry out a rotation. We walk 18 km. The issue of water, food, gasoline is acute. I'm not even talking about heating. The guys are literally freezing in their positions. There's nothing to bring in at all.
