A place where the injury happened can be easily found on a map. Namely, one sees that the location 
"10 km northwest of village Prognoy" is on Ukrainian territory! 

Therefore, servicemen from Russian military unit 51182 entered Ukrainian territory and  clashed with Ukrainian National Guard. A indisputable definition for this is A MILITARY AGGRESSION.
