Modernish Armor Rules
Felbrig Herriot offers his Modernish Armor Rules. The author writes:
These rules came about after deciding to buy some Ultra Modern 1/285th scale models of modern tanks. I couldn’t find any simple quick play rules so after referring to Gulf war anecdotes and of course Janes recognition guides I came up with these. They are simple to use and rely on the common D6.
Universal Soldier Extreme / Modern Day Heroes Rules
RAFM offers a set of free wargames rules for skirmishes: Universal Soldier Extreme / Modern Day Heroes
Universal Soldier Extreme is a set of rules for skirmish level miniature gaming using Rafm Miniatures. The focus of the main rules is on the modern era and optional rules are provided to suit any genre ranging from horror, to pulp fiction, to historical combat. The rules focus on the Modern Day Hero’s line as well as the Cthulthu mythos creatures. The inspiration for these figures comes from the traditional H.P. Lovecraft Horror genre as well as modern movies and cinema. These rules are a skirmish level set of rules. This means that each player would command between five and ten miniatures at a time. Although flexible enough to handle many more miniatures it is up to the players to decide how big a game they desire to play. We have found that a game of this level with two players can be finished in one and half to two hours playing time.
