Operation Sindoor was a test of India's indigenous system against Chinese systems: Warfare expert Spencer

He said the world watched the way India tested its systems.

He said the operation not only displayed India's capability but also showed the will to strike with precision and restraint.

Spencer told ANI that Pakistan is a Chinese-equipped military, so "this is absolutely a test of Chinese military technologies, both for the rest of the world and also for China".

"It (China) uses it (Pakistan) as a lab for this technology...India does share a border with China. Turkey does provide capabilities to Pakistan... Absolutely, a test of those technologies," he said.

"There is an element of proxy warfare where it's kind of geopolitically who has a military defence agreement with whom and what's the extent of it. But absolutely, this is a test of Indian indigenous systems versus Chinese systems. And everybody was learning from that demonstration because war puts everything to the test," he said.

Appreciating India's defence capability, Spencer said: "I studied Operation Sindoor. It wasn't just about the four days. It was what was happening in the decade preceding and the five years preceding, from India's emergence to the Indian military's transformations and preparations, to the small business innovations that were taking place with the technologies and so many elements that were preventing and leading to being prepared for a war. I can't tell you when the next one is because the enemy always gets a vote. But I can tell you that India is more prepared."

Operation Sindoor was launched as a response to the Pahalgam terror attack.. Indian Armed Forces destroyed nine terror infrastructure sites in Pakistan and Pakistan-occupied Kashmir in air strikes on May 7.

Following Pakistan's retaliation, the Indian Armed Forces significantly damaged their air force bases on the intervening night of May 9th and 10th, including Nur Khan base.
