does this have anything to do with the howitzers?

Ukraine launched an offensive Friday to drive out Russian troops in the northeast part of the country.
The two militaries have been engaged in an arduous battle with neither side able to gain the upper hand, The New York Times reported.
However, Ukrainian troops are rallying to form an offensive against the Russian forces, which are pushing toward key cities in the northeast including Kharkiv and Izium.
“There are fierce battles going on, as well as the transition from defensive operations to offensive actions in the Kharkiv and Izium areas,” Ukrainian Commander in Chief Valeriy Zaluzhnyi said Thursday, according to the Times.

The only UA unit I know of that has and is using 777s is the 81st on the east side of the Izyum salient. Since no specifics are included in the quote, its hard to say where exactly the action is - its a big country.
Kharkiv is quite with Orc troops withdrawn to the south in the Izyum area.
No progress in the Izyum salient - shelling as usual continues by both sides. Orc forces spent.
