The were 570 troops on the line which would indicate about 2 battalions of trigger pullers, as a large Russian battalion has about 300 trigger pullers.
Russian serviceman Aleksey Agafonov said they had 3 shovels among them. So obviously in the few hours they had to prepare, they had limited protection from shells, rockets, mortars.
When it was over he wrote:
“When it all started, the officers immediately ran away. In between the attacks, we tried to entrench, but the copters immediately spotted us and just shot us. Out of 570 people, 29 managed to survive, 12 more were wounded, and the rest are all dead”.

That would be 541 dead and wounded. Or 2 Russian battalions out of action. This particular incident, the make up was one of the consolidated groupings which the Russian Command began using after recovering from their “holiday” when they left the north and northeast of Ukraine.
Ref: Before the war, the Russian Naval Infantry (Marines) had a total of 20,000 troops, most of whom were stationed in the Russian Far East.

Agafonov also added that before that, at least one more battalion from the mobilized ones had been defeated in the same positions. Agafonov said that he saw dozens of corpses, some of them “even had soldiers sticking out of their pockets.”
“On TV they show that everything is beautiful, but in fact, here in the Luhansk region, it is the mobilized who are thrown to the front, and when we departed from there, without seeing the officers, we were already walking back, we saw that only contract soldiers and volunteers were sitting on the third line , and mobilized on the front end,” said Agafonov.
According to him, local and contract soldiers do not want to fight, and mobilized people from all over the country are brought to the Svatovo region to close the gaps in the defense. In Svatovo, where the survivors of Agafonov’s battalion retreated after the shelling, “groups of 2 to 5 people” from other defeated battalions go.
“There is complete confusion and discord here. All survivors and new arrivals are grouped into new battalions and thrown to the front to close the line of defense. According to him, the Ukrainians cleared the entire territory where the mobilized fought.
