3-100th Signal Battalion

3-100th Signal Battalion Welcome to the official 3-100th Battalion page. Welcome to the official 3-100th Signal Battalion page. Our Detachment is located at Ft.

MISSION STATEMENT: 3-100th (Signal Battalion), a USAR generating force, executes Career Management Field (CMF) 25 (Signal) Military Occupation Specialty Training and the Technical Phases of Non-Commissioned Officer Education School (NCOES) to develop competent, Lethal, and combat-ready Soldier in support of globally responsive Army and Joint Warfighting commands. The 3-100th Signal Battalion facil

itates 25 series DMOSQ and NCOES training for Soldiers of all Army components wherever and whenever needed. Our unit is primarily comprised of 25U, 25B, 25S, and 25Hs Instructors. The Battalion Headquarters is in Indianapolis, Indiana, located in a newer reserve facility. Knox, Kentucky. Battle assemblies emphasis on instructor training, certification and ex*****on of our training mission. What makes us unique is our flexibility and the opportunities our instructors have to pass on their craft. Since our unit teaches a variety of MOS and NCOES courses, annual training is not a large event held every summer. Rather, it is individually scheduled to meet the needs of the mission and the Soldier. This means an instructor could be behind the podium teaching at Ft. Eisenhower during January or in Sacramento in the fall. With the flexibility of annual training and RSTs, our instructors can tailor their schedule to meet their outside needs, whether it is being a full time student or having a demanding civilian job. The skills learned as an instructor can directly help in any occupation by being able to teach others, give direction, and explain complicated ideas. Along with the flexibility there is the availability to do more than 15 days of AT. Many of our Soldiers choose to go on ADOS-RC orders for longer periods. There is also plenty of promotion potential through all the ranks. In addition, if you live outside of 50 miles, you qualify for lodging in kind to cover a hotel room. Our instructors are on the podium teaching NCOES and reclassification courses. They are able to take their experience coupled with the curriculum and engage their students to give them the tools necessary to be successful signal Soldiers. The history of the 100th Regiment can be divided into two distinct periods. From its constitution in July 1918 as the HQ, 175th Field Artillery Brigade until its reorganization and redesignation in 1959, the 100th was no different than other regiments in the Artillery branch—it deployed during World War II, earned battle honors for three campaigns, and underwent its share of reorganizations and redesignations. After it became HQ and HQ Company, 100th Regiment, an element of the 100th Division (Training), however, it essentially became an administrative unit, with its battalions designated as elements in divisions where they would undergo training. From 1959 until 2008, both the Regiment and its battalions were elements of the 100th Division (Training), but on 1 October 2008 seven of the regiment’s battalions were relieved from assignment to the 100th Division. In September 2009, the Regiment was reorganized so that its thirteen battalions were elements of three different Training Divisions: the 100th (3rd, 8th 11th, 12th Battalions), the 94th (5th, 6th, 7th, and 13th Battalions), and the 102nd (1st, 2nd, and 4th Battalions). (The number of Battalions is not constant, however, and can be increased or decreased to meet the Army’s needs.) Commonly called a unit crest or DUI for short, the Distinctive Unit Insignia of the 100th Regiment was originally authorized for the 375th Field Artillery Regiment on 27 April 1933. It has been redesignated three times since then, starting in October 1942 for the 375th Field Artillery Battalion, in January 1950 for the 375th Parachute Field Artillery Battalion, and lastly in July 1960 for the 100th Regiment. Its shield denotes Artillery, the unit’s branch at the time it was designed. The horseshoe commemorates Virginia Lieutenant Governor Alexander Spotswood’s 1716 thirty-man exploratory expedition that crossed the mountains into what is now West Virginia; at its conclusion, the men were organized and designated as Knights of the Golden Horseshoe and presented with small golden horseshoes in recognition of the organization of the 175th Field Artillery Brigade in Parkersburg, West Virginia in 1921.

Winter Home Safety 🌨️

November brings increased safety hazards as colder weather, holiday cooking, and early darkness raise risks of fire, slips, and accidents.

🌨️ Egress pathways:
Keep exits safe by keeping objects (such as decorations and toys) clear of the exit route. Clear both front and rear exit walkways of snow and ice to avoid slips, trips, and falls.

🌨️ Electrical Outlets:
To avoid overloading electrical circuits on Thanksgiving, plug high-wattage kitchen appliances (such as crock pots and warming plates) into separate circuits to prevent tripped breakers or fire hazards. Avoid using power strips; plug appliances directly into the wall. Calculate amperage by using this formula: Watts divided by Volts = Amps. ex. 1500W / 110V = 13.64A.

🌨️ Food safety:
Keep hot foods hot and cold foods cold on Thanksgiving. Use a food thermometer to ensure dishes reach safe temperatures and refrigerate leftovers within two hours. Leftovers are safe to eat for 3-4 days when stored properly.

🌨️ Emergency Preparedness:
Maintain a box of essential emergency supplies, including flashlights, extra batteries, and portable power banks for charging phones. In addition to non-perishable food, water, and a manual can opener. A first aid kit, personal hygiene items, and pet food and water should also be included.
