From that prior blog entry:
"Allied tanks of NATO vis-à-vis a Soviet opponent and while fighting defensively having a distinctive advantage. Firing from a wedge-shaped ramp able to depress the gun lower than the horizontal. Able to present to the enemy the bare-minimum of target and showing that thickest part of the protective armor in the process."
Allied armor of the NATO coalition having an advantage during mortal combat against the Soviet opponent, tank versus tank,
These images make it clear that the use of a wedge-shaped firing ramp as constructed by combat engineers can give an advantage in tank versus tank combat.
Hull-down firing position with the main-gun of the tank DEPRESSED below the HORIZONTAL!
ONLY a small portion of the defending tank visible to the enemy [the enemy presumably in the open]. And that small portion consisting of the thickest armor, relatively impervious to anti-tank fire.
From these images this is all obvious to even the most casual observers?
During the 1973 Yom Kippur/Ramadan War the Israeli USING THESE WEDGE-SHAPED FIRING RAMPS WITH GREAT SKILL AND EFFECTIVENESS.
I have made this all clear? I hope so.
