Week 9. The ninth week will consist almost entirely of the fundamentals of field firing, in preparation for field training during the tenth week. There will also be a 10 mile march (with packs) during week 9. If you havn't experienced blisters yet during your time in boot camp, you most likely will experience it during week 9.
Week 10. During week 10, you'll start
putting all of your training together during field training. You'll learn the
fundamentals
of patrolling, firing, setting up camp, and more. In the field is also where you
will get your nuclear-biological-chemical (i.e. gas chamber) experience.
