Russia closes Tsentr-2026 with 47,000 troops, 41 delegations — and a second exercise running inside it

Russia's Tsentr-2026 strategic exercise ran from 28 September to 3 October at the Chebarkul training area in Chelyabinsk Oblast, with field activity spread over more than ten training grounds and a naval component in the Caspian Sea. The Kremlin put participation at more than 47,000 service personnel. President Vladimir Putin observed the closing live phase on 2 October, according to the Kremlin's own account of the visit.

Russian state media described it as the country's largest strategic exercise of the year and the most internationally attended. It was also structurally more complicated than the headline numbers suggest: a parallel collective-security drill ran on the same ground, with the same units, under a different command framework.

01What was exercised

Russian officials described the purpose as improving command of troops repelling external aggression, with new weapons and equipment used in practice. Deputy Defence Minister Yunus-Bek Yevkurov told Putin that field exercises were being held at ten training grounds; Chinese-language reporting of the Kremlin material described eleven, including the Caspian component.

The phrasing that attracted most attention outside Russia was about where the scenario came from. In the Kremlin's briefing material for the visit, the exercise is described as drawing, in all its tasks, on the experience of what Russia calls the special military operation.

“All tasks draw on the experience of the special military operation.”

02Who took part

Six states sent military contingents: Belarus, China, Kyrgyzstan, Mongolia, Pakistan and Tajikistan. Kazakhstan and the Republic of the Congo sent operational groups. Russia was the host. A further 33 states sent observers.

03The exercise inside the exercise

Alongside Tsentr-2026, the Collective Security Treaty Organisation held Interaction-2026, a command-staff exercise for its Collective Rapid Reaction Force. The two ran in parallel and on the same ground. Belarusian, Kazakh, Kyrgyz and Tajik units took part in both.

That overlap is the detail that makes the event hard to read as a single exercise. One set of troops, two command frameworks, one training area — and a Chinese contingent inside a sequence convened by an organisation China does not belong to.

04China's contingent

China's contingent was drawn from the Central Theatre Command and organised into three tiers — a directorate, a joint operational campaign command, and task units. PLA Daily reported that the force moved to Chebarkul by road, rail and air, and that the exercise tested joint operational command, long-range strategic mobility and cross-border logistics.

Chinese units took part in the joint live-fire phases: reconnaissance, fires, guided entry, multi-axis assault and rapid clearance. The directorate took part in directing the drill, not only in executing it.

Of the six states that sent contingents, three are not CSTO members: China, Mongolia and Pakistan. The Chinese Ministry of National Defence has described its participation as normal bilateral and multilateral military exchange, and stated that the exercise does not target third parties.

05Pakistan and India

Pakistan sent a contingent that trained alongside Chinese and Russian units and entered the joint live-fire sequence. India, also a Shanghai Cooperation Organisation member and a recipient of an invitation, sent observers only — no troops.

Both are SCO members and both were invited. One sent a contingent into the live-fire sequence; the other sent an observer delegation and no troops.

06The observer list

Thirty-three states sent observers. The list runs from India, Vietnam, Egypt, Indonesia, Saudi Arabia and the UAE to the DPRK, Cuba, Syria, Afghanistan, Mali and Niger.

07What is not known

• The 47,000 figure is a Russian official number. There is no independent verification, and in a command-staff exercise the split between headquarters drill and troops in the field is not visible from outside.
• The Chinese contingent has no published size or equipment list. Numbers and vehicle types circulating online are unverified.
• The training-ground count differs by source: ten in the Russian deputy defence minister's report to the president, eleven in Chinese-language accounts that include the Caspian Sea.
• Interaction levels — how far the two command frameworks were actually fused — cannot be established from official statements alone.
