Reserve components go through a 45 day pre-mob training cycle, yes. Most reserve components don't have infantry units at all, so I'm not sure where you were going with that. Reserve components go through a 45 day pre-mob training cycle. It would work with the Air Force through the Air National Guard just fine. The navy has no presence in land-locked states beyond recruiters, who only take those looking for full-time service. Someone looking to fulfill any such mandatory 2-year term would have to go full-time Navy or pick a different branch. There already is a score system, and favoritism will exist regardless. The score system works by a designated few NCOs (typically the Reediness NCO, the Admin NCO, and the 1st Sargent) looking at everyone's jacket. Those with insubordination flags are cut right away. Then they look at the 'slots' they need to fill. If they only need a medic, and you aren't a medic, you're out. Next up are PT and shooting scores, followed by prior deployments, followed by achievements, followed. My unit handled it by assigning specific pieces of equipment to specific individuals. A lack of personnel is currently a problem, as the shortage leads to unassigned people working on the equipment of others. The reserves is composed mostly of POGs, not grunts. Everyone does the same things during drill anyway. With my unit it's PT every Sat & Sun before duty, and all the same assignments for all the same people. Your typical drill weekend, even for infantry, is inventory, preventative maintenance, and equipment layout; not actual combat training.
