Should polynesian tribes have marines?

[AirikrStrife]

Polynesian were legendary sailors, sailing across huge oceans and the people were excellent boatsmen, should they have access to mariens somehow? or should maybe their base units have marine unit features? Looking at how they are their own tech group it might be solved by that

Sounds reasonable. I imagine there are a number of ways to include this: linked to culture, traditions, government reform, naval doctrine (might be problematic as it requires force limit that may be prohibitive for an OPM).
