I love a different style and focus of wargame. A game that takes a look at an important but somewhat obscure or rarely addressed historical topic, such as espionage or intelligence, and creates a gaming experience tailored around the events to highlight and evoke the difficulties and tension that would have been present. In January 2026, GMT Games announced such a game in Checkpoint Charlie, which is a solo or cooperative game focused on SIS espionage missions in Berlin in the 1960’s designed by Russell Brown. We have posted an interview with Russel and it was very well received and he has now agreed to create a series of History Behind the Cards to highlight the events of the 1960’s Cold War struggle in West Germany but also to share aspects about the game play and how it models the history.
*Note: The cards highlighted in this series and their event text, as well as any pictures used showing any of the various components, are still in the design and development process and as such event effects and text might still change prior to final development and publication. Also the art and layout of the cards are only for playtest purposes at this point and the game will enter the art department as it nears publication.
History Behind the Cards – Checkpoint Charlie from GMT Games – Card #9 Daily Military Train
This is one of the cards I added to Checkpoint Charlie based on conversations with my local coffee shop spy, John (see Card #7). I had assumed most significant traffic from West Germany to Berlin used the autobahn corridor from Checkpoint Alpha at Helmstedt, across East Germany, to Checkpoint Bravo in Berlin. However, the military trains, of which there were three – American, French and British – ran every day, back and forth along roughly the same corridor as the automobile traffic. The US Military Duty Train, which my friend John rode, let out at the station in Charlottenburg and is the basis for this Event Card. It was primarily used by US military personnel, but other people associated with the military could get permission to ride.
Cars full of East German police, or vopos, kept vigilant watch over the autobahn access route, but it was more difficult to keep track of the train and whether western passengers were jumping off illegally somewhere in East Germany, or East German citizens were boarding the train as it slowed for one of its scheduled stops along the way, getting free passage into West Berlin. To solve this problem, all doors on the train were chained and padlocked for the duration of the four-hour journey across East Berlin. In Checkpoint Charlie, the Daily Military Train Event assumes that the KGB has been tipped off to the arrival of some interesting person or item on the next train and move to intercept. Charlottenburg Safehouse is placed under surveillance and the Nugget Marker, already detected, is placed there. This can be a useful diversion for your assets, or it can draw KGB agents right into the center of your mission.
In the next article in this series, we will take a look at Moscow Rules.
In my opinion, this game looks extremely interesting and I am very much excited to learn more about it. I am appreciative to Russell and his efforts to bring us these cards and to write these entries to share with our readers. I am also very glad that this topic is being covered in a game and look forward to playing this one day soon.
