Weapons and combat platforms will remain crucial to warfare, but winning future battles will increasingly depend on how quickly a military can gather information, understand a threat, make a decision and act on it, according to Deputy Chief of the Air Staff Air Marshal Tejpal Singh.

Speaking at a seminar on Tuesday, Singh said modern battlefields and airspace are increasingly defined by "information superiority", network-centric operations and, most importantly, split-second decision-making.

He noted that success in multi-domain operations will depend on shortening the military's OODA loop, which stands for ‘Observe, Orient, Decide and Act’.

What is the OODA loop?

The OODA loop is a continuous decision-making framework consisting of four stages: observing a situation, orienting oneself using the available information, deciding on the appropriate response, and finally acting on that decision. The concept was developed by US Air Force Colonel and military strategist John Boyd. In combat, the objective is to complete this cycle faster than the adversary, allowing one side to make decisions and take action before the opponent can respond.

"The intention is to make our OODA loop shorter than that of the adversary so that we can decide and act before he can," Singh said.

He summed up the objective on the modern battlefield as being able to "sense better, understand faster, decide with confidence, engage precisely and assess continuously".

Why does shortening the OODA loop matter?

Singh explained that while the "act" component of the OODA loop comes from combat platforms and the weapons they carry, the first three stages — observe, orient and decide — depend heavily on surveillance, C4I2 and electro-optical systems.

However, these capabilities cannot function independently if the military wants to make decisions faster.

"We can no longer treat these three aspects, that is surveillance, C4I2 and electro-optics in their own silos. They need to be integrated into a system of systems," he said.

Surveillance systems would serve as the military's persistent "eyes and ears" across land, sea, air, space and cyber domains. Electro-optical systems would provide precision through capabilities such as high-definition thermal imaging, multi-spectral targeting and identification across different environments.

C4I2 (Command, Control, Communications, Computers, Intelligence and Information) would act as the "central nervous system", integrating these capabilities and fusing information from different sensors into real-time, actionable intelligence and situational awareness for battlefield commanders.

Singh described such integration as not merely an engineering objective but a "combat multiplier".

He pointed to the experience of designing and operating the Integrated Air Command and Control System (IACCS), where sensors, communications and shooters are integrated.

Greater reliance on network-centric warfare also creates vulnerabilities. Singh warned that as such operations accelerate, the networks themselves could become targets for adversaries.

He stressed the need for standardised protocols, interoperability and self-reliance in modern communication systems.

Ground sensors, combat platforms and aerial intelligence, surveillance and reconnaissance assets need to operate on the same networks and "speak a common digital language", he said.

Modern networks will also face cyberattacks, electronic warfare and spoofing. The C4I2 backbone, therefore, needs to be "self-healing" and resilient enough to operate even in dense electronic warfare environments.

Singh said the future of warfare would continue to involve weapons and platforms, but would increasingly be won through information, integration and faster decision-making.
