Russian military expert Andrey Marochko has reported heavy losses for Ukrainian forces over two consecutive weeks, citing data from the Russian Defense Ministry. In reports published on July 13 and July 20, Marochko detailed manpower losses exceeding 9,900 and 10,000 respectively, along with significant destruction of military equipment and drones. The reports, carried by the Russian state news agency TASS, attribute the heaviest battlefield damage to Russia's Battlegroup East operating in the Dnepropetrovsk and Zaporozhye regions.

Coverage Comparison

Both reports originate from TASS and rely exclusively on the analysis of Andrey Marochko, a military expert who said he based his conclusions on Russian Defense Ministry data. The first report, dated July 13, covers the period ending that week, while the second, dated July 20, covers the following week. The two accounts provide similar assessments of Ukrainian losses but with notable differences in the numbers of destroyed equipment.

The first report states Ukrainian losses amounted to approximately 9,940 killed and wounded, including foreign mercenaries. The second report, reflecting a later week, puts the figure at about 10,155, which Marochko noted was 215 higher than the previous period. Both reports emphasize that Russia's Battlegroup East inflicted the greatest manpower losses on Ukrainian forces.

Regarding equipment destruction, the reports differ in specific counts. The July 13 report mentions nearly 5,000 Ukrainian fixed-wing UAVs destroyed, along with two tanks, three multiple rocket launchers, 59 field artillery pieces, 38 electronic and counter-battery warfare stations, and over 570 combat vehicles. The July 20 report lists 4,600 drones, three tanks, eight unmanned boats, three multiple rocket launchers, 48 field artillery pieces, 38 electronic warfare systems and radars, and nearly 600 combat vehicles. These discrepancies may reflect different reporting periods or evolving assessments.

Key Claims

Manpower losses: According to Marochko, Ukrainian forces lost over 9,900 service members and mercenaries in the week ending July 13, and over 10,000 in the week ending July 20, with the latter being 215 more than the previous week.
Battlegroup East's role: Marochko credited Battlegroup East, operating in the Dnepropetrovsk and Zaporozhye regions, with inflicting the heaviest manpower losses on Ukrainian forces.
Equipment destruction – July 13 report: Russian forces destroyed nearly 5,000 Ukrainian fixed-wing UAVs, two tanks, three multiple rocket launchers, 59 field artillery pieces, 38 electronic and counter-battery warfare stations, and over 570 combat vehicles.

What was claimed, and who backed it

AI-extracted; can misattribute a claim — see Methodology.

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
