British OB

[clarkmj111]

In Both Beyond Normandy and Panzer Lehr, the British OB will say X 8 6 pdr Or X 8 Firefly (and a few others where this is relevant
But in the Beyond Normandy British OB on Vassal, you always have an option to take a solid shot version, or a superior HVAP option.
Both modules have very similar Soecial Rules sections, but this difference is not discussed in either.

Instinctivyl i felt that in late 1944, HVAP would be available - but then it occurred to me that why have the solid shot in the Vassal counter mix at all?

Similarly - the scenarios will say 1 8 Achilles, but the counter mix has Achilles 3 inch and Achilles 17 pdr options

So, how to decide?
