Western countries have scrambled to deliver billions of dollars of military gear to Ukraine. Getting it to the frontlines is a whole other problem.

• Western countries have sent Ukraine billions in military aid since Russia attacked in February 2022.
• Getting that aid to Ukraine has been one problem, but getting it to the frontlines is another.
• For a military at war, it's a challenge to get the right gear to the right troops at the right time.

The Ukrainian military and public's will to fight was a key reason that Russian President Vladimir Putin's plan for a quick military victory failed last year, at times making up for Ukraine's disadvantages in troops and equipment.
