The 2028 Indian infantry problem

The Indian Army has the largest standing infantry force of any democracy. That is a reputation and a resource. It is also, in the operational tempo of the last three years, an exposed surface. Every casualty taken in Poonch, every prolonged engagement in Manipur, every high-altitude rotation in Ladakh and Arunachal traces back to a common training gap: the distance between a battalion's last full-fidelity exercise and the conditions it is asked to operate in on deployment.

Three terrains, one training shortfall

Urban — Poonch and Rajouri

The ambush patterns seen in Poonch since late 2023 — closed compartments, elevated fields of fire, limited immediate reaction options — are not unique to the sector. They are the structural geometry of any Line-of-Control settlement. Training for them demands section-scale CQB repetition: stack discipline, buddy-pair overwatch, post-contact manoeuvre. A live mock-up of a Poonch compound exists, at scale, in precisely one location. Every battalion that rotates through the sector cannot train there before its rotation.

Jungle — Manipur and the Northeast

Dense-canopy terrain rewards one set of tactics — movement-contact, quick breaks of contact, flanking under restricted observation — and punishes another. Jungle is also the terrain in which communication discipline matters most, because visual cues are available at a distance of metres, not hundreds of metres. Training this is expensive and geographically constrained. Units rotate into active sectors without ever having rehearsed a jungle movement-contact drill at their current orbat.

Mountain — Ladakh and Arunachal

The high-altitude theatre imposes not just tactical constraints but physiological ones. Reaction times slow. Decision quality degrades with cumulative altitude exposure. The only way to build resistance to this degradation is rehearsal under representative cognitive load — and the only practical way to generate that load outside a deployed environment is synthetic.

Why live training can't absorb this

A typical Indian Army infantry battalion trains for two to three major live exercises per year. Each consumes a week of live-fire time and costs several lakhs in expendables, range fees, transport and safety overhead. The result is a heavy, infrequent rehearsal cycle that does not match the operational tempo it is supposed to prepare for.

Synthetic training does not replace the live cycle. It fills the gap between cycles. A section that runs one live urban exercise every six months should be running forty synthetic urban exercises in between, because muscle memory decays on a timescale measured in weeks, not quarters.

Muscle memory decays on a timescale measured in weeks, not quarters. A force that trains live twice a year is not a force that trains twice a year. It is a force that loses muscle memory ten times a year.

What section-scale synthetic actually looks like

SHAURYA-SIM was built around three observations drawn from conversations with serving infantry officers.

• First, training must happen at the unit of engagement — the section of twelve soldiers. Individual-skill simulators exist but do not rehearse the thing that fails in combat, which is section coordination.
• Second, weapon-mounted inertial tracking is non-negotiable. Nothing else replicates the ergonomics of cover, movement and engagement at the fidelity required for muscle transfer.
• Third, instructors must author scenarios themselves. Scripting pipelines that require a software team are scripting pipelines that never get used. A platoon havildar should be able to build and run a drill in under twenty minutes.

The backlog argument

By 2028, every infantry battalion rotating through an active sector will face at least one of three conditions: urban engagement, dense jungle, or sustained high-altitude deployment. Many will face all three in a career. The cost of preparing them synthetically, expressed per soldier per year, is smaller than the cost of any other training intervention available. The cost of not preparing them — expressed in the same units — is not budgetable.

India's infantry is the largest in the democratic world. It should also be the best-rehearsed. The tooling exists. The doctrinal case is made. What remains is the decision to make synthetic training standard, not supplementary.
