Are there ways to attract enough soldiers without a draft?

How about a Universal Conscription system where everyone must serve but only volunteers become foot soldiers or go overseas.

Drones, robots, AGVs, cyber- and robotic systems reduce the need for soldiers.

he soldiers of the future might be made up largely of specialists and experts to deploy and operate these powerful systems.

Changing the requirements from operating a rifle to operating a screwdriver or logic analyzer.

Changing the work location from a battle front in another country to a building in the US or on a military base or ship, separating the soldiers physically from the battlefield

The free training and reduction of personal risk might attract more voluntary soldiers.

The military could also rely on contractors, service depots and outsourcing instead of soldiers to maintain the robotic equipment in many cases.
