To make matters worse, French Ordnance Note G:
This note implies the presence of a low ammo counter.
See also, Chinese Ordnance note 7 and Chapter K (fewer ammo boxes), The question is whether low ammo status (circled B#) is the equivalent for manhandling purposes. The rules imply that the low ammo status is equivalent and it makes sense. But the chart clearly requires the counter.
I disagree. I don't think French MAON G and Chinese ON7 (or Chinese MAON D) imply the presence of a Low Ammo counter. The Guns in question do not begin play with a B# and X# lower than that printed on their respective counters.
I think there's some confusion between the increased vulnerability of a Gun to having a Low Ammo counter placed on it, and the actual condition of "Low Ammo."
Keep in mind that
all Guns can suffer from the Low Ammo condition. Some, however, are susceptible to having Low Ammo counters placed on them as a result of a TH DR. The majority only acquire Low Ammo counters when they opt to discard ammo in order to increase their mobility.
Therefore a Gun with a circled B#, whether printed on the counter or otherwise assigned, does not begin play with a Low Ammo counter. This is consistent with the rules as spelled out in A19.131: "All... Guns...
during an Ammunition Shortage... which already have a circled B# start play with a Low Ammo counter already in place."
Consequently, these Guns are not eligible for the -2 DRM for Manhandling a Gun under a Low Ammo counter until such time as a Low Ammo counter is actually placed, either deliberately or as a result of a sufficiently high TH DR.
