A required minimum distribution applies only to pension plans where you have an option as to how much you can withdraw, such as Individual Retirement Accounts (IRA's) and 401-K plans. The purpose is to require you to take distributions so you can pay tax on the money you put away for retirement, that was not taxed when you earned it. The type of pensions you describe would normally have a predetermined distribution amount, and if so the RMD rules would not apply.
