  • Ukraine's ammo shortages are also affecting its US-made HIMARS, an American veteran told BI.
  • Soldiers are now having to pass on targets they once would have hit, he said.
  • Ukraine has had to get "more and more selective with their targets," giving Russia an edge.

Ukraine's insufficient supply of ammunition means its soldiers can't hit the targets they want with even their most effective weapons, a US veteran now fighting in Ukraine told Business Insider.
