A CPP is one VGC, typically consisting of a driver, vehicle commander, and gunner.
The purpose of GT II, or the crew proficiency course, is to prepare the VGC for live-fire qualification.
VCEs must consider multiple factors when scoring a VGC, including the different timing matrices based on the vehicles' posture (defensive or offensive).
Table 1 is a comparison of the total monthly rate for four different private line services--the terrestrial digital circuit or TDC, the voice grade circuit or VGC, a 9.6 kb/s Dataphone Digital Service (DDS), and a 56 kb/s Dataphone Digital Service.
Over 1,000 miles, VGC prices are essentially unchanged.
Thus, to make an "apples-to-apples" comparison, the line labeled "48 VGC" in Figure 3 assumes all 48 circuits have C-5 conditioning.
