Hello future soldiers, I am going to give you a low down on how basic really is from my experiences at Ft. Sill!
PT: You will wake up at 0500 Mon-Sat and have first formation at 0530. You will do PT from 0600-0700. PT consists of Pushup/Situp drills, 4-4 the core ( Ab workouts), and 30/60', 60/120's, or ability group runs on run days. Do NOT doubt your physical ability. I was one of the people who was literally freaked out about the idea of all the physical activity I was going to have to endure. Reality: We hardly ever got smoked, the physical activity is at a minimum (Drill Sergeant and Battery dependent). Of course, the more you exercise before you ship out for basic the better you will do.
Barracks: In my barracks we had 57 people. This number solely depends on the amount of people in your platoon, or if you share with another platoon as I did. The barracks at Ft. Sill are pretty spacious. You will have room to move about and won't be too cramped up. Shaving- If you are in one of the barracks with a lot of people, wake up early; there are only a limited amount of sinks/time. SHOWER! Nobody wants to smell you, trust me. Ft. Sill is incredibly hot during the summer (100+), you will smell of sweat and body odor. Don't be that guy who everyone says smells. Fireguard- You will occasionaly throughout the week have to pull fireguard. Fireguard is merely walking around the barracks acquiring a headcount/cleaning.
Food- The DFAC at Ft. Sill is actually pretty good. You have time to eat, don't choke yourself. They have types of food for everyone.
Heat- Drink lots of water! Stay hydrated! You WILL be out in the sun for a long period of time and will lose most of your water through sweat.
Ruck Marches- Rucking was the worst part of BCT for me. Tell your parents/friends to send you shoe inserts for your boots, initial issue boots arent that great. Buy padded socks for the PX if you easily get blisters, which I did. You will do a 4,6,8,12, and 16K. Don't be scared however, you will be rucking a lot inbetween those marches and will get used to it. In all honesty, the 4k was the worst for me!
Gas Chamber- Don't be afraid of this, yes it isn't a pleasant experience, but it doesn't last very long. Take shallow breaths, the bigger the breath you take, the more it will hurt.
Basic Rifle Marksmanship- Learn the four fundamentals and know how to implement them! Don't be trigger happy, make sure you're aiming at the right place.
Drill Sergeants- All DS's are different. Some may be nice, some may be more "mean". They however will not treat you wrong. They are your leaders and teachers, respect them and pay attention! Stand at parade rest when talking to one and always have a battle buddy! Respect them and they will respect you.
Tricks of the trade: Sleep in your sleeping bag! By doing so, you will not have to make up your bed every morning, trust me, its time consuming! Merely place it on top of your bed and sleep in it! While doing Ruck Marches, find a way to place your rifle that makes it the least heavy while making it still at the position of Low Ready. DFAC- If you eat fast enough, your DS's may allow you to go for seconds! Do PT on your own in the barracks, it will greatly help you out on your PT test!
In conclusion, BCT is not as bad as it is made to seem. It is all a mental game. Get over the thought of not being able to do it, you can! BTW- Reception is incredibly boring at FT. Sill, be prepared to be there for more than three days! HAVE FUN! You will make life long friends there, enoy this experience while it lasts.
Open to questions, ask away!
