True, the Army training is the same for all, the only difference is that after all the schools, or between some of them, the person is a part of a Reserve or Guard unit.
Some are softer than the regular military, some are tougher, some are better than their active duty counterparts.
Reserve and Guard SEAL units, Special Forces, Rangers and such, are good units, I don’t know what it is like now, but the Guard used to have better pilots and tank operators, and medical people in the Reserves. Take two tanks, one driven by a team that have been active for 3 years, the other who were also active for three years, but for the last dozen years they have all been on the same tank in their Guard unit, they get hard to beat.
