Crediting of Military Service in Non-Military DB Plan

[Guest mwspaid]

I have a client (a small independent nation loosly affiliated with the US) who is establishing a new defined benefit plan (for its government employees). The client wants to allow up to two years of service with any branch of the US military to count toward vesting service but not benefit service.

The client is concerned that somehow this might jepordize or at least reduce any US military pension a member might be entitled to.

I have told them this is not a concern regarding vesting service.

Is there any circumstance where crediting service with the US military in a non-military defined benefit plan could cause problems with a military pension?

Thanks,

Mike
