To recruit a new army in the documented Ashes of the Singularity II demo, press R to open New Army Recruitment. Choose the opening units and plan where the army should assemble so its first units arrive from suitable production nearby. For an army already in the field, use reinforcement rather than starting a second group.
Open New Army Recruitment
The official February demo hotkey list assigns R to the new-army recruitment menu. Start by deciding what you need the new army to do. A force intended to cover a separate approach needs its own assembly point, while replacing losses at the front calls for reinforcing the existing army.
Put the initial rally point near useful production
The developer journal on evolving production describes new-army production as starting from an eligible facility near the initial rally point. Put that point where the first units can assemble without a long trip through contested territory.
The later production feedback update describes manually setting the rally point and seeing a line leading to the facility that produces the first unit. That update distinguishes its later interface from the automatic rally behavior used earlier.
Reinforce a field army without creating a new one
After the army has its first unit, the later update describes the army itself as the reinforcement rally point. That destination moves with it. The journal also explains that existing armies get reinforcements from suitable production close to their position. Check where the army is operating before choosing whether to expand nearby production.
