Ukrainian troops are calling the US military in the middle of shootouts with Russia for help fixing their artillery

• The US military is leading a team that is helping to repair Ukraine's military hardware over the phone. 
• These virtual exchanges often take place during battle, the Associated Press reported.  
• Ukrainian troops, meanwhile, are pushing artillery systems to the limits to keep Russia at bay.

As Ukrainian troops push their Western artillery to the limits, and sometimes past them, while fighting off Russian forces, the US military is helping to repair broken down pieces over the phone and through video chats.
