Mark Milley, and the Ukraine Defense Contact Group Friday at Ramstein Air Base this week to discuss military aid packages for Ukraine aimed at thwarting an expected Russian offensive in 2023.The Biden administration is currently working to finalize a new weapons package of nearly $2.6 billion worth of military aid for Ukraine, which may include approximately 100 Stryker combat vehicles and 50 Bradley armored vehicles, according to the Associated Press.Ukraine’s top military intelligence official, Kyrylo Budanov, warned Russia earlier this month that Russia should expect attacks “deeper and deeper” inside Russia.German Chancellor Olaf Scholz has said that Germany would be willing to approve sending German-made Leopard tanks to Ukraine if the U.S. provided Abrams tanks as well, according to Süddeutsche Zeitung."
