It's not part of the "Modern ASL" group's work under Frank, though - looks like an independent work. Not a surprise, of course, I'm sure that goes on all the time. Does look interesting. I've been part of the MASL group for awhile and even wrote a Vietnam scenario - and playtested it, albeit a couple years ago now. The MASL stuff is an interesting compare and contrast to what is shown here, but I won't say more than that since it's all still being worked on.
If anyone picks this up, I hope they'll share their thoughts on it with us.
Incidentally, I am obviously in the camp that if any historical period saw fighting between groups of men divided into what we know as "squads", then ASL can reasonably be used to recreate that fighting. The last two years of the First World War, Vietnam, even Iraq all fall into that category - the technology is just window dressing to the tactics of the men. Recreating how the technology is a matter of how complicated do you want the layers of rules - ASL players have shown they have no great resistance to complicated rules, so there is really nothing stopping anyone from recreating any time period.
