From https://bulgarianmilitary.com | By TOC | Feb 15, 2024.

"In a strategic move to enhance its artillery firepower, the Ukrainian Armed Forces‘ Logistics Forces have embarked on the repair of M777 155mm towed howitzers."

"This significant news was announced by the Command of the Logistics Forces. Leading these restoration efforts are repair specialists who are utilizing advanced technologies like titanium surface welding to repair damages in the artillery systems."

"The Ukrainian military released a video that provides a glimpse into the intricate process of howitzer repairs, demonstrating the meticulous tasks involved in servicing these formidable weapons." 

Johnny-on-the-spot welding of titanium difficult to do. Ukrainian resourceful and adaptable. Cannot wait for unit to be repaired at a depot with all the delay that will be involved.

M777 the record Ukraine not so superlative? Excessive delicacy being a demonstrable flaw?
