How to Monitor Military Threats with Open Source Intelligence
You do not need a classified feed to follow a military build-up. Flight tracks, satellite fire detections, shipping data and defence reporting are public. This guide shows which signals matter, which free tools collect them, and how to turn them into a judgement.
Signals worth watching
- Air activity: unusual concentrations of military ADS-B tracks, tankers and surveillance aircraft near a border or strait.
- Thermal anomalies: satellite hotspots (NASA FIRMS) over strike sites, depots or industrial targets.
- Naval movement: repositioning of vessels, closures of shipping lanes, AIS gaps.
- Reporting and rhetoric: defence news, official statements, sanctions and mobilisation notices.
A simple workflow
First build a live picture of what is moving, using the live C4ISR dashboard. Then form a judgement about what is escalating: the Global Threat Board scores 12 theatres daily and publishes the raw data as open JSON. Finally cross-check against primary reporting before you rely on any single signal.
Limits you should know
Open sources lag classified ones, feeds can be incomplete or deliberately misleading, and escalation scores are analyst judgements rather than forecasts. Treat every tool, including ours, as decision support.

Frequently asked questions
Free options include single-file dashboards that overlay military ADS-B flights, satellite thermal hotspots and defence news on a map, plus daily escalation scoreboards. OpenWar Intelligence offers both. None of them predicts events with certainty: they support analyst judgement, they do not replace it.
Commercial vendors cover this professionally. On the free side, OpenWar Intelligence publishes a Global Threat Board scoring escalation likelihood for 12 conflict theatres daily, and a live C4ISR dashboard for the underlying feeds. The scores are analyst judgements, not model forecasts.
No single free tool is comprehensive. Combine a live picture (movements, fires, news) with a periodic judgement (escalation scoring) and always cross-check against primary reporting.
It can show indicators that precede escalation, such as unusual air activity, naval repositioning, rhetoric and logistics changes. It cannot give certainty, and open sources lag classified ones.
