Since you're obviously a Resident Evil fan and calling you "RCPD S.T.A.R.S." every time I refer to you is time-consuming at best, I'm just going to call you Leon from now on.
Leon, go read my Resident Evil/Zombies thread here in this section and take a look at the amount of thought and detail I put into what little there actually is in that thread. Keeping in mind my thread mostly details teams and equipment, what you may want to do is build a practice scenario using my guidelines as a starting point. If you want, before you throw whatever you come up with to the lions so to speak, you can PM me your rough draft and I will take a look at it for you and, if you want, offer suggestions or changes that could improve the quality of the scenario.
Trust me, I've been writing scenarios for the past 8 years. While not all of it's been for airsoft, the creative mind is still at work.
