Who are these people dropping into New York's sewer system?

The NYPD are baffled by the motive of the people who enter the sewers, leave no trace and seem to pose no threat to the wider public.

Preparedness means having an emergency kit ready to go in case of emergencies. On the first day of hurricane season, make sure you’re ready with:

💲Cash

🐶Pet supplies

Mexican authorities say they found a 869-foot tunnel in Tijuana that likely connects to a well-known street in San Diego. https://t.co/fJIFbY4606

Destroying tunnel entrances - in Iran or elsewhere - does not work. Because it is so difficult to destroy underground facilities, they must be destroyed before they become unattainable. #tunnels #underground https://t.co/jjy6kK5Blm

Exercise Arrcade Strike isn’t just boots on the ground 🪖

It’s computers, comms, logistics, and signals all working together to keep operations moving and @NATO strong.

This is modern defence in motion 🫡

[RUSI @RUSI_org]

Our latest report by @roberttollast and @Jack_Watling says that the UK is approaching a critical military juncture following decades of defence disinvestment while potential adversaries, Russia and China, have accelerated modernisation of their forces at scale.

Russia now spends approximately US$500 billion annually on defence in purchasing-power-parity terms, funding sustained weapons upgrades informed by battlefield data gathered in Ukraine, including hardening missile navigational systems against electronic warfare and other Western countermeasures. China is increasingly fielding classes of weapon where there is no direct analogue in the UK, Europe or even in the US.

The paper does not conclude that technological inferiority is inevitable, but makes clear it is increasingly plausible, and that planning as though it will not occur is a dangerous assumption.

An endless "whack-a-mole" style fight — monitoring the pipes for exit holes, taking out the Russians that emerge, filling in the holes, then searching for the next and newest exit point. #subterranea @MilGeoscience

[The Kyiv Independent @KyivIndependent]

In the new era of a drone-dominated battlefield, the Russian army is taking advantage of an extensive system of underground Soviet-era infrastructure, using it as a drone-proof route to push troops forward.

@Stu_Lyle @JaysonGeroux Given buildings might already be in a precarious state of structural repair, interesting to note the roof fall vs lack of helmets 🪖
Can’t have a structural engineer in each team, but worth some basic education on reading ‘combat integrity’ of a structure prior to pulling pin.

It's 37°C IN THE SHADE on our patio this afternoon. If you are one of those utter idiots walking your dog you are clinically insane. And cruel. No dog has ever died NOT having a walk...

We’ve long tried to control the weather by engineering rainfall. Now such cloud-seeding efforts are escalating, creating conflict between countries and stoking conspiracy theories. But do they work? https://t.co/CBhne3UVdY

It's actually hiding one of Syria's biggest underground fortunes.

ARRCADE # STRIKE !

Cracking background; how @HQARRC used some of #London’s extensive #subterranean #infrastructure to protect an #HQ element.
Huge effort from a broad cast of specialists to enable, sustain, and #operate.

@pinstripedline Astute call by @pinstripedline.
Lots of moving pieces, literally & metaphorically, to enable and sustain an #underground facility.
Worth recognising that many of the specialists required, with deep (pun absolutely intended) are Reservists.
Rail, power, water, fuel, geology…

[Sapper Geologist @SapperGeologist]

Absolutely brilliant to see the use of #underground space ⚒️
One of many themes being evaluated as we look at how to better #protect our forces.

British soldiers are fighting a Russian invasion from a platform on the London Underground in a wargame that reveals the UK must invest much more in defence - or risk defeat

We've been conducting a major @NATO exercise in London this week - and no one above ground suspected a thing.

Hundreds of soldiers have been testing how they would run a major NATO command post, hidden deep beneath one of the busiest cities on earth.

While Ukraine 🇺🇦 is fortifying, the Polish 🇵🇱 and Baltic 🇪🇪🇱🇻🇱🇹 defensive lines have barely been started, even though they have been planned for a long time.

I have checked a good part of the borders with Russia and Belarus and no defensive preparations are underway, with the exception of the reinforcement of anti-migrant barriers.

However, the threat is real. In the aftermath of the war in Ukraine, if the status quo persists, Moscow will have an army of 1.5 million troops, thousands of tanks, ballistic missiles, millions of FPV drones, and hundreds of thousands of Geran-type attack drones.

The Baltic Sea will obviously be a Russian priority, both to consolidate control over Kaliningrad and Belarus and to expand access to the sea. Faced with the American withdrawal, only a military guarantee will prevent Moscow from intervening; this requires fortifying the borders, with priority given to key roads leading to major cities.

[Clément Molin @clement_molin]

These last 2 months, Ukraine 🇺🇦 dug 1 300 km of fortifications from Kyiv to Odesa

In the eastern part of the country, the AFU can now rely on 2 to 6 defensive lines, with kilometers of obstacle lines extending behind the front.
