This wasn’t an invasion. It was France preparing for one.
What Marie witnessed was just a small piece of something much bigger brewing across France. Her country is gearing up for ORION 26, the largest multinational military exercise on French soil since the Cold War ended decades ago.
ORION 26 represents a dramatic shift in how France thinks about defending itself. Unlike traditional military exercises hidden away on remote bases, this massive drill will unfold across real French communities, highways, and coastlines starting in early 2026.
“French planners are treating ORION 26 less as a simple drill and more as a national-scale dress rehearsal for a major war,” explains defense analyst Captain Laurent Moreau. The exercise builds on lessons learned from ORION 23, which mobilized over 12,000 French and allied personnel across three months in 2023.
But ORION 26 promises to be bigger, bolder, and more realistic. French tanks will share roads with civilian traffic. Fighter jets will practice combat maneuvers over actual cities. Naval vessels will coordinate coastal defense alongside commercial shipping routes.
The scenario driving this massive undertaking? A high-intensity conflict against an adversary with comparable military technology and resources—essentially preparing for war against another major power rather than the counterinsurgency operations that have defined recent decades.
ORION 26 will showcase France’s military capabilities on an unprecedented scale. Here’s what makes this exercise so significant:
| Aspect | ORION 23 | ORION 26 (Projected) |
|---|---|---|
| Personnel | 12,000+ | 15,000+ expected |
| Duration | 3 months | Extended timeline |
| Participating Nations | Multiple allies | Expanded coalition |
| Operational Domains | Land, air, sea, cyber, space | All domains integrated |
The exercise will test France’s ability to coordinate across multiple military domains simultaneously:
“What sets ORION apart is its realism,” notes military historian Dr. Sophie Rousseau. “Soldiers have to navigate real traffic jams, deal with actual weather conditions, and work around civilian communications networks. It’s messy, complicated, and exactly what modern warfare would look like.”
The timing and scope of ORION 26 reflect France’s evolving security concerns. The exercise directly responds to changing global threats, particularly the return of great power competition and the lessons learned from recent conflicts in Ukraine and elsewhere.
French military planners have watched how modern warfare has evolved. Today’s conflicts blend conventional military operations with cyber attacks, space-based assets, and information warfare. ORION 26 prepares French forces for exactly this type of multi-domain battle.
The exercise also tests France’s ability to defend its homeland while maintaining its role as a key NATO ally. French citizens living near exercise areas will experience firsthand what military mobilization looks like—something most Europeans haven’t witnessed since World War II.
“We’re not just training soldiers,” explains Colonel Jean-Pierre Lavigne, a logistics specialist involved in planning. “We’re testing how well our entire society can function when the military needs to use civilian infrastructure for defense purposes.”
For communities across France, ORION 26 will bring temporary disruptions—road closures, increased air traffic, and the sight of military equipment moving through their neighborhoods. But it also brings economic benefits through increased military spending and heightened security cooperation with allies.
The multinational aspect cannot be overstated. ORION 26 will strengthen France’s defense relationships with key allies, demonstrating interoperability and shared commitment to European security. Partner nations will deploy significant forces to France, creating one of the largest allied military gatherings in Europe since the Cold War.
ORION 26 sends clear signals beyond France’s borders. The exercise demonstrates French military capabilities to both allies and potential adversaries. It shows France’s commitment to territorial defense and its ability to host and coordinate large-scale allied operations.
For ordinary Europeans, ORION 26 represents a return to thinking about conventional warfare on European soil—something that seemed impossible just a few years ago. The exercise acknowledges that peace cannot be taken for granted and that maintaining it requires serious military preparation.
“This isn’t about warmongering,” emphasizes security analyst Dr. Antoine Leclerc. “It’s about deterrence. The best way to prevent war is to be visibly prepared to fight and win one.”
The exercise will also test France’s civilian infrastructure and government services under stress. How well can hospitals, transportation networks, and communication systems function when the military needs priority access? These are questions that hopefully remain theoretical, but ORION 26 will provide concrete answers.
What exactly is ORION 26?
ORION 26 is France’s largest multinational military exercise since the Cold War, scheduled for early 2026 across French territory, involving thousands of troops from France and allied nations.
Will civilians be affected by the exercise?
Yes, civilians may experience temporary disruptions including road closures, increased military air traffic, and the presence of military equipment in their communities, but these will be carefully managed and communicated in advance.
Which countries will participate in ORION 26?
While the full list hasn’t been announced, the exercise will include multiple NATO allies and partner nations, building on the international cooperation seen in ORION 23.
Is this exercise a response to specific threats?
ORION 26 reflects France’s adaptation to evolving global security challenges and the return of great power competition, rather than targeting any specific nation.
How does ORION 26 differ from previous military exercises?
Unlike traditional exercises confined to military bases, ORION 26 will use real civilian infrastructure, roads, and airspace, making it more realistic and comprehensive than previous drills.
What will the exercise cost?
Exact costs haven’t been disclosed, but the exercise represents a significant investment in French and allied military readiness, with economic benefits for communities hosting the activities.
