I did 4 drills prior to shipping to Basic. They followed pretty much what Rycass linked to. First drill was all about Military etiquette, such as coming to attention, standing at parade rest, marching, saluting and so forth. Every drill had some form of PT both Saturday and Sunday and some classroom type learning as well as some outdoor learning.
One drill we did rappelling, another we did paint ball, a third we practiced various movement and shooting techniques and tossing a dummy hand grenade. The final drill we didn't get to do this fun stuff. Instead for those of us shipping in the next month we finished paperwork and prepared for shipping out.
As was previously stated, every state will be different. I hope this helps.
