Canon has a few offensives in 1998.

(quotes from V1 Referee's Manual)

1998
In late June, the Pact forces in southern Germany renewed their offensive in an attempt to seize the scattered surviving industrial sites in central Germany. Actually, the most intact parts of Germany were those areas in the south which had been under Warsaw Pact occupation, as neither side was willing to strike the area heavily. Galvanized into renewed action, NATO forces made a maximum effort to reform a coherent front, and the Pact offensive finally stalled along a line from Frankfurt to Fulda. In late August, NATO launched its own offensive from the area of Karl Marx Stadt, driving south to penetrate the Pact rear areas in Czechoslovakia. The thinly-spread Czech border guard units were quickly overwhelmed and Pact forces in central Germany began a precipitous withdrawal to Czechoslovakia, laying waste to southern Germany as they retreated.

1999 was pretty quiet.

1999
In Europe, the fronts were static for most of the year. Low troop densities meant that infiltration raids became the most common form of warfare. The "front" ceased to be a line and became a deep occupied zone, as troops settled into areas and began farming and small-scale manufacturing to meet their supply requirements. Local civilians were hired to farm and carry out many administrative functions in return for security from the
increasing numbers of marauders roaming the countryside.
