Field & Training Expectations

Field & Training Expectations

Built in 1917 as Camp Jackson, Fort Jackson is known as a training post, so if you are here, expect a lot of field time. It trains about one-third of all new soldiers, so chances are, someone you know in the Army knows a lot about the weather here. For official information, save this link for the National Weather Service.

It’s never comfortable in the field, but the hot summer and colder winter nights can make the experience worse if you don’t prepare. The post may issue warnings, but it is always good to check before planning for a field op. The Army won’t always cancel training for severe weather though they may issue alerts such as flag conditions. In severe cases, training can get canceled if the risk outweighs the benefits.

  • Some things to keep in mind:
    Hydration is key, no matter what the weather, but especially in the hotter parts of the year
  • Waterproof your gear, the rain can be unforgiving and wet gear is never fun
  • Heat injuries are totally preventable, so monitor yourself and your fellow Soldiers
  • If you have any questions, be sure to talk to your medical unit or the field medics

In short, use your best judgment in preparing for the worst. Remember, your health and safety are paramount! Check in with yourself and your teammates as you are out there training.


Keep all of these in mind as you prepare to make your move to a new posting. It’ll help you with your practical moving needs and clothes packing. Consider some recreational gear because of the outdoor activities you can do in this temperate climate. If you are a Soldier at Fort Jackson you’ll be in the field a lot. Do your best to prepare by preparing for hot and cold weather conditions before stepping off. Preparation and hydration are key!
