The header row lists the guns the document covers: 85 mm D5-85-BM (factory #9), 85 mm D10-85, 85 mm S-34-IV (TsAKB), 122 mm S-34-II (TsAKB), 122 mm D-30 (factory #9), 122 mm BL-9 (OKB-172), 122 mm S-26-I (TsAKB), 130 mm S-26 (TsAKB), 152 mm BL-10 (OKB-172), and the 122 mm BL-13-1 (OKB-172).
The second row shows the vehicle class the gun would have been mounted on. The first three 85 mm guns are for medium SPGs (presumably, it just says SU). The next two 122 mm guns are for the Object 701 (IS-4) and IS-6 respectively. The next 4 guns of various calibers are for heavy SPGs (same, but ISU). The last gun is marked for the IS-6, but crossed out.
The next row is for the muzzle velocity of the shell, AP (top) and HE (bottom). The row after is for maximum ranges. The range of most guns in the ISU is limited by the gun's elevation, rather than the propellant.
After that is what we came here for, the penetration values. The numbers for the D-30 are similar to that of the D-25 we have seen in previous tables. The penetration of the BL-10 is a little lower than the value in the first article of this series; it has been reduced by 4 mm at 100 meters, and also drops off faster.
The D5-85-BM, on the other hand, received a marginal improvement. The D10-85 blows it out of water with penetration surpassing that of the slower 122 mm guns. The S-34-IV performs similarly.
The line after that is the rate of fire. After that, ammunition capacity. After that, crew members in the gun's vehicle.
