That depends. If the two members have different ranks or titles, then there are 14P2 = 182 ways.
This way would mean that a pair of members like Jesse and Frank is different from Frank and Jesse.
If the two members are untitled and otherwise indistinguishable, then there are 14C2 = 91 ways.
This way would mean that a pair of members like Jesse and Frank is the same as Frank and Jesse.
