As DARPA and other military research organizations create crazy new technologies for the battlefield, the military will have to start training service members to start using and maintaining these capabilities. Here are five jobs that the military doesn't need today but will tomorrow.
1. Beekeepers and trainers
The military began training bees to detect explosives and defeat IEDs, but they will also be useful for finding mines when the U.S. is fighting other nation states. Bee keepers will work in anti-mine and counter-IED teams to identify probable buried explosives. Since the bees' training wears off after after a certain period, trainers will stay on forward operating bases to re-certify colonies. The bees move around the battlefield on their own, so these troops will rarely leave their bases.
The military already has cyber defenders and has discussed the possibility of some of those troops conducting limited counter-attacks to network incursions. This won't be enough for long. Future enemies will have robust networks and drones. Maneuver commanders will need intelligence that can be stolen from enemy networks and will need enemy drones taken out as part of a planned assault.
They won't need network defenders for this, they'll need network attackers. These troops will likely stay on a well-defended base, possibly in theater for faster connection to the enemy's network.
3. Forward drone controller
Every U.S. military branch has dedicated drone pilots with the Air Force's being the most famous. But as drones become more intelligent, a second branch of drone operators will be needed. Rather than piloting the machines, they will input simple commands for the drone to move to a point or patrol a designated area.
These service members will go forward with patrols and control semi-autonomous drones in support of a platoon leader's commands. There will be both walking and flying drones capable of ferrying supplies, surveilling key terrain on a battlefield, or carrying indirect fire radar or sensors to detect enemy muzzle flashes.
4. Robotic systems maintainer
With the military getting robotic pack mules, robotic hummingbirds, and robotic people, they're going to need dedicated mechanics to service the equipment in the field. Robotics systems maintainers will mostly replace whole parts and send damaged pieces to vendors for repair. They'll likely operate like vehicle and generator mechanics do now: small teams will deploy to outposts when required while most maintainers will stay on forward operating bases or larger installations.
5. Powered armor maintainer
Currently, damaged body armor is simply replaced from stocks in supply. For expensive and complicated suits like the TALOS, this won't be a viable option. Powered armor maintainers will operate like computer/detection systems repairers, working in a secure location to replace and repair damaged components. Powered armor maintainers may even be able to focus on the mechanical parts of the system while allowing computer/detection systems repairers, who already maintain a wide variety of electronic systems, handle any software or electronic issues.
Bonus: Jetpack qualifier
While it won't be a separate job, certain units will field new DARPA jetpacks to allow soldiers to quickly move on the battlefield or for scouts to break contact if discovered on a mission. Going to jetpack school will be a privilege new recruits could enlist for or re-enlisting soldiers could choose. Like airborne or air assault schools, some graduates would go on to serve in units where they actually need to know jetpack warfare while others would just attend training for the cool skill badge and promotion points.
