Due to the ongoing Sino-American War in China I could see the US government putting effort into developing new weapons technology, power armor variants/modifications/equipment, vehicles, and other endeavors to quickly win the war and increase the survival ability of the troops. I could also see the US constructing either manned or unmanned bunkers that would be used to house personnel or store needed military hardware, supplies, and ordnance on the off-chance of a Chinese Invasion by sea or air with several existing bunkers like the Greenbrier being reactivated for service whilst being expanded... there could also be the chance of bunkers being built in places like the Patton War museum or other museum to house not only current model vehicles but the needed factory equipment to make ammo and spare parts...
Power Armor Variants-
As seen with the Medic Power Armor I could see the next version including the use of an internal pharmacopoeia injector that when needed automatically injects the needed drug into the wearer's body to heal or boost up by Psycho or Jet... I could see a Pre-War inhalant drug similar to Jet being made but never saw field deployment.
What about variants with a greater strength boost above 2 or because of deployed troops in China certain mods were added to those suits like a Self Destruct or Electro-Shock
PIP-Boy Variants- Because of the success behind the PIP-Boy model the US military saw the benefit of a military version for soldiers but never saw field deployment.
