Telegraph: A clever trick used by Ukraine to shoot down Russian planes. Writer David Ax stated that the Ukrainian Air Force continued its unprecedented shooting down operations of Russian fighters last month.

He continued to say that the Ukrainians took some components of the three American-made Patriot missile batteries - their best air defense batteries - and organized them into mobile units. It appears to be this tactic that allowed the Ukrainians to shoot. down several Russian planes late last year, while amounting to a preview of the bloodiest February campaign.
