QS = Quick Scoot capability – Self-propelled artillery units that can shoot
and then very quick drive off to a new location. These units have a greatly
reduced chance of not being around when counter battery fire falls.
Shouldn't it be more along the lines of "These units have a greatly reduced chance of still being around when counter battery fire falls."
The original quote seems to indicate that the Quick Scoot capable units are more likely to be hit by counter-battery fire.
