[The] Army clearly wants the Bradley to remain survivable and deadly in the toughest combat environments—even if that makes a bit more challenging to transport it to the battlefield in the first place.
There is little point having a vehicle light enough to fly off to distant battlefields if it just dies once it gets there when faced with enemy systems as heavy as the enemy wants them to be.
The 6-7 infantry versions and the cavalry version will get more computing and engine power.
It will also have more capacity to resist mines. And more electrical power. The vehicle should also get active protection systems.
An A5 version is planned for the mid 20s that will upgrade the cannon to 30mm, add armor, and stretch the vehicle to hold 8 infantry. It will reach about 40 tons.
It is hinted that a remote weapon station will be added to suppress enemy infantry near the vehicle.
I'd like to see some modified with wing-mounted machine gun remote weapon stations manned via reachback technology in order to keep the infantry more secure in the rear during advance to contact when the destruction of a Bradley could lead to the deaths of all the infantry and crew in a catastrophic explosion. Although it is said that the infantry inside will have far more protection.
But maybe only one RWS is needed.
Also, the forward observer version will be upgraded.
The infantry fighting vehicle is an interesting blend of a lethal vehicle that can destroy enemy armored vehicles with its gun and anti-tank missiles and carry infantry more safely to battle under armor. The cavalry version carries just a couple scouts to dismount as needed.
