In that quote Reserves would have to be trained harder because they have to be trained just as hard as the Regular Forces, but in less time (because you don't liive on a base).
This has gone far too long......
The reserves are not harder. They have some unique challenges, like balancing a civie job and your reserve job (makes for some long stretches of days without a day off), but it is not harder than the regs, its different.
This debate is like debating which country has the best special forces unit, or which Ghost Recon character is the best soldier, or who's dad could beat up whos dad....it's silly and its not possible to come to any agreement. It's personal choice and personal experience, but in the end it's totally irrelavant.
