Huh.
Huh huh huh. Thought this was straightforward, but now...
It was always my understanding that the "Smoke" column on the Chapter A divider was referring only to smoke
grenade capabilities. It was never my understanding that it applied to OBA smoke.
Oh, I see -- I just realized that the chart on the Chapter A divider is titled "A25 National Capabilities Chart". That means it is there to summarize / provide-quick-reference-for the various rules in Chapter A25. Those rules clearly state the smoke
grenade capabilities of each nationality, and say nothing about OBA smoke (at least in my 1st edition ASLRB). Therefore, the "Smoke" column equals the "What kind of smoke grenades?" column.
The American section does specifically address the special Plentiful Ammo OBA rule... so if there were any special OBA Smoke rules for nationalities, they would be (probably) be in A25.
However, there is one specific SMOKE rule that isn't, which is A24.3:
"WP is a special form of SMOKE commonly available only to the U.S. player, although the British also have it commencing in 1944 (use by other nationalities is limited to SSR)."
Even here, the way the rule is written suggests that it only covers smoke grenades... However, C8.6 then refers OBA/ordnance WP effects back to A24.31-.32, so we know the
effects go beyond smoke grenades. That doesn't mean A24.3 itself necessarily covers WP OBA availability, though!
The more I think about it, the more I think the ASLRB never actually covers the subject, and that's why SSRs handle it (if they're properly written... and if they aren't it generates a Q&A!).
Looking back at the SL rules, I see that the guiding principle was that any OBA could fire smoke. Every rule I looked at in the ASLRB seemed to
imply that any OBA can fire Smoke, without saying it explicitly.
Sorry, but any further research would require more extensive rules-digging than I have time for tonight...
