The Tactical Combat Series (TCS) wargames were first published by The Gamers and now by MMP.
(from MMP website:)
The Tactical Combat Series (TCS) brings the detail of small unit combat to the gaming table.
Taking the role of Battalion or Company commander, TCS requires players to skillfully plan their assaults and their defenses through written Operations Sheets (Op Sheets). Units must follow orders as outlined on their Op Sheets. Unexpected circumstances can require split second decisions. Making these decisions is the easy part. Getting the orders to your troops, however, is another matter entirely.
