brigade TOC System Overview
|
Table 5-1. Brigade TOC Operations |
|
o Monitor Airspace Management and Operations |
|
- Display air defense /TMD unit locations and coverage's |
|
- Display airspace management |
|
- Receive and display air picture from multiple sources |
|
- Receive TBM launch information from joint force or corps commander |
|
o Conduct intelligence preparation of the battlefield (IPB) for air defense situation |
|
- Display enemy unit locations and likely avenues of approach, potential TBM launch sites, etc. |
|
- Establish priorities and assess defense effectiveness |
|
- Use intelligence for preemptive strikes/planning |
|
o Display Common Integrated Air Situation |
|
- Provide near real-time air situation for ABTs and TBMs |
|
o Pass Engagement Orders to Patriot Battalions and/or other Air Defense Shooters |
|
o Monitor Engagement Operations |
|
o Support Scheme of Maneuver Development |
- Using IPB, imagery, and air defense situation display, determine friendly areas not protected, partially protected, or fully protected. |
|
- Pass via MSE link those areas to the battle planners |
|
o Monitor and Display Friendly Ground Situation |
|
o Warn Friendly Forces |
|
o Record and Display ABT and TBM track history |
|
o Reduce Sensor-to-Shooter Time Line |
|
o Assess Inputs from National Intelligence Assets |
|
o Display Selected Enemy Order-of-Battle (OB)/Fuse Display relevant to Intelligence |
|
o Record and Display ADTOC Operations |
