Military equipment was much simpler and could be produced much more rapidly back then. The sophisticated stuff with which our military currently is armed has much longer lead times for production. So we’d have a massive number of universal conscripts, but without the equipment necessary for them to contribute to the war effort.
Relatively small drones can be enormous force multipliers for an armed civilian population.
Drone operators can be useful at home or abroad. Drone operators should be armed with easily concealed firearms, so they can avoid being targets when off duty.
All of this should be connected to communications which will be effective if grid power is down, such as with encrypted Starlink capability.

Just think of the Clint Eastwood flicks in the 70’s-nostalgic.
