In a release published this week, the USAF has announced that maintainers will be allowed to wear shorts in lieu of ABU trousers when temperatures exceed 80 deg F.
Nellis AFB Airmen paved the way starting in the summer of 2019, wearing commercially produced shorts for work on the flight line. Now, the change will be force-wide.
According to the upcoming directive, “Authorized areas (for wear) will include the flight line, hangars and dock areas outside of climate-controlled areas. If commanders authorize the wear of the shorts, they will meet specified requirements that will be incorporated in the upcoming change to AFI 36-2903 for standardization and be worn with the coyote brown T-shirt and uniform green or coyote brown socks with uniform boots.”
But the upcoming change that will effect all Airmen is authorization of ball caps. The recent virtual uniform board recommended procurement of a “tactical cap” which will take approximately a year. The delay is because the cap will have to be Made in the USA and the vast majority of caps which units purchased in the past were not Berry compliant. This is an example of those caps which were worn while deployed to CENTAF.
Another welcome change for many, Airmen and Guardians in all specialties will be authorized to wear their functional community’s approved duty identifier patches. The identifier will be a maximum of five letters and maintain a standard spice brown color scheme. Here’s an example:
The Air Force also announced these changes:
Airmen and Guardians will also have more options for sock colors, glasses frames and bags carried in uniform. Service members will be able to wear conservative, solid black, white, navy blue, gray, desert sand, tan, Defense Logistics Agency?issued green or coyote brown socks with their physical training gear. The socks may have small trademark logos. New guidance for eyeglasses and sunglasses will allow more color options for frames to include black, brown, white, navy blue, gray or transparent material, or gold or silver wire. Finally, additional options for bags and bag colors will be authorized. Messenger and lunch bags will be permitted, and the following colors will be approved for all bags to be carried in uniform: black, brown, gray and navy blue. All authorized bags must be without design, unless ABU or OCP pattern.
Members will be also authorized to wear cold weather accessories without wearing authorized outer garments. For example, the fleece cap and/or gloves may be worn without an outer garment. Headphones or Bluetooth devices may be authorized in more environments. Wear or use of an earpiece, any Bluetooth wireless technology or headphones while in uniform, indoors or outdoors, is authorized for official duties or may be authorized as determined by the installation commander, delegable no lower than the squadron commander level.
These changes are set to take effect on 15 March, once the service updates Air Force Instruction 36-2903, Dress and Appearance.

ABERDEEN PROVING GROUND, Md. – Material scientists from the U.S. Army and Department of Energy conducted a study of plasma-treated aluminum nanoparticles with the goal of improving future propellants and explosives.
Researchers from the U.S. Army Combat Capabilities Development Command, known as DEVCOM, Army Research Laboratory, and the Center for Nanoscale Materials at the Argonne National Laboratory, investigated a new class of surface-engineered aluminum nanoparticles. They published their findings in the peer-reviewed Journal of Applied Physics for a special issue, Fundamentals and Applications of Atmospheric Pressure Plasmas. The journal featured the article on the cover of its Feb. 14, 2021, issue.
“The ultimate goal of the effort is to extend the range and disruptive power of Army weapon systems,” said Dr. Chi-Chin Wu, a materials scientist at the laboratory. Wu leads this effort and is the first author of the article. “The paper presents results that support of ongoing investigations of aluminum nanoparticles for use as novel energetic ingredients in propellant and explosive formulation.”
The study exploits plasma-based surface treatment and chemical synthesis techniques, she said.
“Images and data obtained from two state-of-the-art transmission electron microscopes at the Center for Nanoscale Materials at the Argonne National Laboratory revealed valuable information on oxide shell phase transformation and the dispersive nature of the deposited carbonaceous materials,” Wu said. “This provides tremendous insight for further optimization.”
The new plasma approach enhances the reactivity of commercial 40-60 nanometer particles. For comparison, a human hair is typically 60,000 nanometers in width. According to Wu, the method involves first treating with a helium plasma to etch away a significant portion of their inert oxide shell and then treating with a helium/carbon monoxide plasma to deposit a reactive surface coating.
“Plasma science is a fascinating emerging technology for many applications but has yet to be sufficiently explored in the energetics community,” she said. “All this is done in a custom dielectric barrier discharge plasma reactor. The resultant particles were then characterized by high resolution transmission electron microscopy revealing important nanoscale surface and chemical composition features. We are constantly seeking new energetic materials with higher energy densities and faster energy release rates.”
Plasma treatment and synthesis, coupled with comprehensive material characterization, is critically important for optimizing methodologies and materials for scale-up and transition, she said.
Dr. Rose Pesce-Rodriguez, also from the laboratory and a co-author of the study, said the plasma approach developed by Wu has opened new possibilities for the U.S. Army to effectively surface-engineer metallic nanoparticles for energetics applications.
“Aluminum is just the first example,” Pesce-Rodriguez said. “Since 2018, several parallel efforts involving in-house, DOD, DOE and academic collaborations have blossomed. Making headway on this problem is difficult because samples are so small and require specialized technology to image and analyze.”
According to Pesce-Rodriguez, the microscopy tools available at DEVCOM-ARL and Argonne enabled Wu and collaborators to do a “remarkable job” of characterizing the new plasma-treated particles.
“We’re looking forward to more exciting discoveries,” Pesce-Rodriguez said. “It seems we’re learning something new almost every day.”
Wu said her ultimate goal is for DEVCOM-ARL to develop and transition energetic materials through a unique combination of innovative plasma technologies and advanced materials characterization techniques.
Collaborative partners in this study are Drs. Jianguo Wen and Ilke Arslan at the Center for Nanoscale Materials, Argonne National Laboratory.
“It’s been great to collaborate with Dr. Chi-Chin Wu and her team on advanced disruptive energetics,” Wen said. “This gives Argonne the opportunity to bring our expertise and unique capabilities to challenging Army problems.”
Dr. Mark Tschopp, the regional lead of ARL Central in the Chicago area, said this is a great example of collaboration between the Army and the Department of Energy.
“It combines the expertise of scientists at both laboratories along with unique facilities at the Department of Energy User Facility Center for Nanoscale Materials,” he said. “Expanding the Army team to include other partners is vital to tackling some of the fascinating and challenging science that the Army Research Laboratory is pursuing in areas such as at the intersection of energetics and plasma science.”
According to Wu, the work is an example of how the laboratory is working to operationalize science to provide energetics for transformational advances.
“It brings material science expertise into energetics for advancing future weapon systems,” she said.
The U.S. Department of Energy, Office of Science, Office of Basic Energy Science supported use of the Center for Nanoscale Materials, an Office of Science user facility, under an existing contract.
