Abstract:
A war games land mine, comprising:a gas-release module, including: a gas-release module housing, said gas-release module housing defining a first gas-flow pathway therein; a gas source mounted within said gas-release module housing and having a gas under pressure therein, said first gas-flow pathway extending to said gas source; and a trigger assembly positioned in association with said gas source and configured for releasing said gas from said gas source and into said first gas-flow pathway; and a marker-source module positioned in association with said gas-release module, said marker-source module including: a marker-source module housing defining a second gas-flow pathway therein, said second gas-flow pathway being in fluid communication with said first gas-flow pathway and thereby being configured to receive said gas released from said gas source, said marker-source housing including a primary container, said primary container configured for retaining at least one marking agent therein, said primary container having a delivery nozzle fluidly coupled therewith proximate a distal end thereof; a piston movably mounted in said primary container, said piston defining one end of a containment region for the at least one marking agent within said primary container, said piston having a first piston side and a second piston side, said second piston side being configured to be positioned adjacent the at least one marking agent and to be actuatable thereagainst, said first piston side being in fluid communication with said second gas-flow pathway, said first piston side thereby being configured to be impacted by said gas released from said gas source in a manner sufficient to cause at least a substantial portion of the at least one marking agent to be expelled through said delivery nozzle; and a plurality of o-rings between said piston and said primary container, said plurality of o-rings encompassing said piston, said plurality of o-rings engaging both said piston and said primary container.
