US veteran in Ukraine says Russia is the 'alpha predator on the battlefield' now because of ammo shortages

• Russia can be the battlefield "alpha predator" due to Ukraine's ammo shortages, a US veteran said.
• Ukraine can usually use artillery to let its infantry advance and take on Russia, he said.
• But the shortages mean Ukraine can't do this and has to instead ration what ammo it does have.

Ukraine's ammunition shortages are allowing Russia to be the "alpha predator on the battlefield," a US veteran fighting in Ukraine said.
