In heterogeneous battlefield teams, the balance between team and individual objectives forms the
basis for the internal topological structure of teams. The stability of team structure is studied by
presenting a graphical coalitional game (GCG) with Positional Advantage (PA). PA is Shapley
value strengthened by the Axioms of value. The notion of team and individual objectives is
studied by defining altruistic and competitive contribution made by an individual; altruistic and
competitive contributions made by an agent are components of its total or marginal contribution.
Moreover, the paper examines dynamic team effects by defining three online sequential decision
games based on marginal, competitive and altruistic contributions of the individuals towards
team. The stable graphs under these sequential decision games are studied and found to be
structurally connected, complete, or tree respectively.
