The U.S. Army announced on Tuesday that troops could face discipline if they are not fully vaccinated against COVID-19.

The big picture: The deadline for U.S. Army troops to be vaccinated is Dec. 15. 40% of Army troops had been fully vaccinated as of late August. National Guard units have until June 30 next year to meet the vaccination deadline.

What to expect: "While soldiers who refuse the vaccine will first be counseled by their chain of command and medical providers, continued failure to comply could result in administrative or non-judicial punishment — to include relief of duties or discharge," per an Army statement.

What they're saying: Lt. Gen. R. Scott Dingle, the U.S. Army surgeon general, said in a statement that the Army introduced the measure as coronavirus case "counts and deaths continue to be concerning as the Delta variant spreads."

Army begins offering smaller armor sizes

The U.S. Army is now handing out armor in three new sizes — extra small short, small short and small long — to address complaints primarily from female soldiers and smaller-stature men about fitting into the equipment, AP reports.

Driving the news: The move comes after some complained that traditional armor sizing can be cumbersome and hinder some soldiers' movements. It highlights the fact that more women have moved into combat roles that were traditionally reserved for men, AP notes.

Scoop: Jake Sullivan discussed Saudi-Israel normalization with MBS

White House national security adviser Jake Sullivan raised normalization with Israel during his recent meeting with Saudi Crown Prince Mohammed bin Salman, three U.S. and Arab sources tell Axios.

Why it matters: Saudi Arabia would be the biggest regional player to sign onto the "Abraham Accords" peace agreement with Israel, and such a major breakthrough would likely convince other Arab and Muslim countries to follow suit.

Tech's leaky world

Tech companies are learning what everyone in Washington already knows: Leaks of confidential info are inevitable, and "plumbing" operations to close them rarely work.

Why it matters: Most tech firms talk up the power of transparency but prefer to keep details of their operations secret from competitors and the public. Researchers, regulators and the media are increasingly relying on information provided by dissident employees and whistleblowers to see inside companies' workings.
