There were 3 editions of Gulf Strike published:
First Edition (1983) included two 22 x 32" mapsheets, two 22 x 16" mapsheets (incorrectly described on the box as three 22 x 32" mapsheets) and 910 counters (sheets 1-4, with sheet 4 being 130 units).
Second Edition (1988) included a new 16-page Scenario Update booklet, an additional mapsheet (Map D) and countersheet 5 (130 units), bringing the contents up to two 22 x 32" mapsheets, two 22 x 16" mapsheets, one 8 x 22" mapsheet and 1040 counters (sheets 1-5, with sheets 4 & 5 being 130 units).
Third Edition (1990) included the 2nd edition contents and added the Desert Shield - A Gulf Strike Expansion Module, comprising a 12 page Desert Shield scenario booklet and a new 260-piece countersheet, bringing the contents up to two 22 x 32" mapsheets, two 22 x 16" mapsheets, one 8 x 22" mapsheet, and 1300 counters (sheets 1-6). The number of counters included in the 3rd edition is incorrectly stated on the box (1430) - there were only 1300 (4 x 260 plus 2 x 130).
There was also a "2.5 Edition", which had the 2nd edition box but included the Desert Shield - A Gulf Strike Expansion Module, release in 1990. Only some of the later / last copies of the 2nd edition were released with the Desert Shield Expansion Module - these were identified with a black & white sticker on the box cover. The 2nd edition with Desert Shield Expansion Module is identical in contents to the 3rd edition.
There was an additional Desert Storm mapsheet and 40-piece die-cut countersheet included with The GENERAL Vol.26,No.6 (see below).
