JCATS is an entity level constructive simulation. Commanders can use JCATS for purposes similar to MTWS.
JCATS can model units down to the individual level, providing a higher level of resolution than MTWS. Typically, MTWS better suits the MAGTF warfighter's training needs, but JCATS provides better fidelity for certain training applications. For example, a unit who desires to use a UAS platform cannot see entities in MTWS, so JCATS is a better fit.
The BSC accomplishes UAS feeds using Virtual Reality Scene Generator (VRSG) or Night Vision Electronics Sensor Toolkit (NVESD).
