Gamble loads a magazine before attempting to "zero" the M4 carbine rifle using the backup iron sights. During Week 2, the trainees begin to fire rifles with live ammunition.

Zeroing a firearm is adjusting the sights so the bullet hits where aimed.
"I'm learning new things every day. It gets harder as we are given more responsibilities, but talking with my family has kept me positive and motivated. I still feel like I made the right decision."
Gamble spends some of his personal time to reading a letter from family. For 30 minutes daily trainees get "personal time" in which they can do what they choose. Generally the trainees spend the time washing clothes, writing or reading letters or cleaning weapons.
Reading this letter really makes me miss home and miss my family. But, at the same time it makes me want to stay here and finish what I started.
