The Ukrainian forces used rocket and artillery bombardments and airstrikes to halt the Russian advances.[1] The State Special Communications Service of Ukraine reported that one of these artillery strikes destroyed a convoy of Russian armored vehicles they designated as "Group V" (due to the letter "V" marked on the vehicles) and that over 100 units of equipment were destroyed.[12][13] Ukrainian forces also destroyed a bridge connecting Bucha and Irpin to prevent more Russian ground forces from entering Irpin.[4]
