Military Service Acts during the war? Where can I find them?

[potty5]

Dear forum members, this has probably been covered several times, but can't find the exact answer I require, so is there anywhere I can go to view the different stipulations of the four military service acts during the war i.e. ages of the men who enlisted. Been trying to find these figures for a while. Thanks alot.
