Tactical Game 3 had an impact that reverberated for years. SPI and Avalon Hill batted the concept around for years. Here is an early entertaining but flawed iteration from the early 70s as the system is applied to then contemporary warfare in western Europe. The game would ultimately be replaced by the ambitious Mech War 77.

As suits a game of this sort where scenarios are ahistorical, the game relies heavily on contemporary military documents and organizational layouts. Scenarios explicitly list on-paper elements as well as idealized conflict situations meant to illustrate doctrine.

The game is a remarkable change from the series games up to this point. Most noticeably, the board is large, with few hills, divided into a number of sections. Infantry and artillery include their vehicular component in a single counter. Ranges for HE weapons can be as large as 72 hexes. Helicopters can move swiftly across the board with relative immunity. TOW offer enormous AP attacks that can guarantee destruction of armored units.

There are also odd rules. TOW units disappear after firing. Units may also triple their fire for single turn then disappear as well. There were a bunch of other complaints addressed in a sheet of errata including the unpardonable sin of missing a counter for a scenario. One complaint was that the Russian forces were modeled on outdated and incorrect data that left the Russians far too weak.

The game of course hints at changes to come. Soon, SPI would introduce their SiMove system while covering a range of WWII theaters. The final iteration of the system would be October War designed by Mark Herman who would go on to rewrite the system as Mech War 2.
