Deepest position is fullback, IMHO, but it's also the one that requires the most depth. Davidson and Woolfolk are a solid and proven 1-2, and Macek proved his worth with 1 hundred-yard game last year as well. From all reports, Holt is challenging for time and there are a couple of others with game experience; so there's plenty of reserve.
The OL appears to be particularly strong at the two guard positions. Not as certain about the depth at center and tackle, but the starting lineup is as good as any Army has fielded in recent years.
In fact, the only questionable position on the offense is TE. All the others are a solid two deep at least.
Couldn't ask for much better than Aukerman at SAM with Wolf as a solid and proven backup.
