As Russia refuses to back down from the threat of invading Ukraine, US troops have been put on heightened alert for possible deployment to Europe.

This move includes Army brigade combat teams as well as logistics, medical, aviation and transportation units.

Defense Secretary Lloyd Austin issued the order to units now in the US that would be part of a NATO force if the alliance decides to activate a military response.

This comes as NATO meets to discuss the situation in Ukraine and Russia's recent actions. It is still unclear whether or not US troops will be sent to Europe, but the heightened alert shows that the US is taking the Russian threat very seriously.

Biden's comments the other day insinuating that there is such a thing as a "minor" invasion may well have tipped the scales on the current tension. Only time will tell.
