BREAKING:
Russian Defense Minister Sergei Shoigu announces the creation of 2 new ground armies, with 16 new brigades & 14 new divisions
As @noclador points out, that’s more than the combined armies of 🇩🇪🇬🇧🇫🇷🇵🇱🇪🇸🇳🇱🇸🇪
Post-election mobilization is coming
Some of the U.S. troops made the jump after a 17-hour direct flight from Alaska. Others gathered earlier in the day at U-Tapau, about 250 miles south of the jump zone.

Absolutely wild footage, this is a real world engine failure in a MD500 (Think Magnum P.I. helicopter) over Kauai, Hawaii out on a tour flight.
You’ll probably have to watch this a few times but the video starts out with the helicopter under power and then the engine sound goes silent. The beeping you hear is the engine-out audio beep to inform the pilot that engine power has been lost.
This maneuver that pilot is doing is called a Autorotation and the way to think about helicopter flight, the engine is turning this big fan (rotor blades) on top of the body and sucking in air from the top and projecting it downward to overcome the force of gravity.
When engine power is lost, you experience a reverse in airflow because now gravity takes over and the air flow is coming from the bottom of the main rotor disk. The only thing the pilot can really do is to make sure the rotors keep spinning by changing the pitch of the rotor blades through the use of the “collective” which is a lever next to the pilot’s left leg and it only moves up and down.
The pilot has to manipulate the collective during an auto rotation to make sure the blades keep spinning. If the pilot pulls up too much on the collective, the rotor blades will bite too much of air causing a resistance and slow the rotors down. If the pilot doesn’t pull enough collective.. the blades will speed up and potentially cause a catastrophic failure.
The other control the pilot has is called the cyclic. This cyclic sits between the pilots legs and and manipulates individual pitch of the rotor blades to tilt the rotor disk aka “big fan” and make the helicopter go forward, backwards, left, right. So essentially in this type of emergency, you have to manipulate the controls in a delicate balance because no matter what, gravity is taking you to the ground because the engine is no longer producing power.
The pilot did an outstanding job here given the geography and limited amount of flat terrain to put the helicopter on the ground.
Thankfully it sounds like no souls were lost and only one injury according to a news report (see the link below)👇 Of course there is a lot more to helicopter aerodynamics but I’m trying my best to put this in simpler to digest terms. Big thanks to @Combat_learjet for sharing and definitely worth a follow!
We remember many events from our training at RMC but without fail Shaggy Ridge is the most prominent. Designed to expose in us and our teammates our resiliency it continues to be an excellent platform to inform the determination of those who deserve to lead our soldiers.
Exercise Shaggy Ridge is a mentally and physically demanding exercise designed to test the strength, character and resilience of our Staff Cadets at the Royal Military College - Duntroon. Shaggy Ridge kicked off this week for II Class.
Mark Mankowski argues the division as highest echelon of command for @AustralianArmy. Part 1 considered measures he considers necessary to reinforce the division, this post discusses more formations in enabling 1st Division.

33 years ago today, Operation Desert Storm began.
This story was published on the 30th anniversary but it is as timely as ever:
30 years after Desert Storm, an Air Force general says we’ve forgotten the lessons that made it so successful:

To all those “I stand with Yemen 🇾🇪” idiots, are you aware that the official internationally recognized government of Yemen is fighting the Houthis?
You don't stand with Yemen. You stand with a terrorist organization that has murdered over a hundred thousand Yemeni civilians.
