Tactical Combat Series

Tactical Combat Series (TCS) wargames was first published by The Gamers and then now by MMP.

(from MMP webpage:)
"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."
