B-GL-309-006/FT-001 First Clash was required reading when I was a subaltern and I think I was issued a copy shortly after meeting the Adjt. When B-GL-309-007/FT-001 Counterstrike was published I read it, not as good, probably because of the change to Fantasians from Soviet. Timing was fortuitous, was getting ready for Staff College, otherwise I would not have read it I assume. Interest in it was minimal I think.
Neither book was as well recieved in the CAF as outside. That trend continues, more recently, Crisis in Zefra was panned in the Army but the USMC ordered more copies than the CA in one single order.
