Ukrainian forces face major supply shortages

Saturday's Odesa drone attack comes as Ukrainian troops are rationing ammunition and salvaging parts in order to keep up the fight against Russia.

Ammunition stocks are dangerously low on the eastern frontlines, along with other crucial supplies needed to keep the war effort moving. 

CBS News was taken to an undisclosed wooded location not far from the battlefield, where a small team of mechanics have been working around the clock to fix damaged Humvees. It's like a triage for battle-worn military vehicles. 

They have put more than 100 of these American-made vehicles back into the fight in the month of February alone. 

The vehicles that cannot be saved are stripped down for spare parts. Ukrainian soldiers cannot afford to waste a single thing, cannibalizing radiators, drive shafts and suspension springs.

They are a maintenance, repair and overhaul unit, modeled on a U.S. military system they were trained under.

Maj. Ihor, the MRO unit's commander, tells CBS News that that lately, it's been getting "more and more difficult" to get new parts for these vehicles.

"We critically need more parts," he says.
