N40R is N46L sister aircraft, it also carries a CEASAR pod. The A200 variant used may be a C12-A or a C-12C (this is the model number visible on N40R fuselage). They are also known as Huron and HC-12.
The CEASAR, which stands for communications electronic attack with surveillance and reconnaissance, is a rectangular metal box that holds technology capable of both knocking out cell phones and radios and intercepting transmissions, while an electronic warfare officer onboard speaks directly to troops on the ground. It’s precise enough to cover friendly soldiers while jamming insurgents, but not knocking out communications for an entire village near a given operation.
