Speaking of training and maintenance I found this post at RealClearDefense by Lolita C. Baldor interesting:
A MILITARY BASE IN SOUTHEASTERN POLAND (AP) â€” On the front lines in Ukraine, a soldier was having trouble firing his 155 mm howitzer gun. So, he turned to a team of Americans on the other end of his phone line for help.
â€œWhat do I do?â€ he asked the U.S. military team member, far away at a base in southeastern Poland. â€œWhat are my options?â€
Using phones and tablets to communicate in encrypted chatrooms, a rapidly growing group of U.S. and allied troops and contractors is providing real-time maintenance advice â€” usually speaking through interpreters â€” to Ukrainian troops on the battlefield.
In a quick response, the U.S. team member told the Ukrainian to remove the gunâ€™s breech at the rear of the howitzer and manually prime the firing pin so the gun could fire. He did it and it worked.
The exchange is part of an expanding U.S. military help line aimed at providing repair advice to Ukrainian forces in the heat of battle. As the U.S. and other allies send more and increasingly complex and high-tech weapons to Ukraine, demands are spiking. And since no U.S. or other NATO nations will send troops into the country to provide hands-on assistance â€” due to worries about being drawn into a direct conflict with Russia â€” theyâ€™ve turned to virtual chatrooms.
Modern telecommunications certainly change the landscape of battle, don’t it?
