Yeah, the helicopter insertion is ridiculous. Dynamic entry for a slurpee! Are you out of your mind? Been watching too many Rambo flicks?
I do, however, like the claymore/rabid rotty method, although I use a different approach. It would work in a pinch, though I must remind you that even a rabid rotty can be fairly easily circumvented by an operator with the right equipment (or a bag of sandwich meat).
My team and I (always travel in fire teams with at least a weapons specialist, sniper/designated marksman, a medic, a commo, and a demo guy) first circle the convenience store a few times, making the passes as inconspicuous as possible. The sniper (sierra one) then picks his spot. We then exfil the area and allow the sniper to reinfiltrate to the hide. This sometimes takes only 10-15 minutes but could take a few hours. You must not get impatient and attempt to rush the sniper in his reinfiltration of the target area. THE SLURPEES WILL BE THERE WHEN YOU GET THERE. Trust me, they won't run out.
Once sierra is in position, he can call in the rest of the team. We park our team van (it's a black van with a wing and a orange stripe on it) several blocks from the convenience store. For those smarty pants that must inevitably ask, yes we do tactically park our tactical A team van but the KEY is that we are many blocks from our intended target. Our tactical approach is made on foot, with normal tactical formations and with far more tactical awareness than we could possibly have while resting within the shag-carpeted walls of our van.
We then split the remaining members (all shooters regardless of specialty) into red element and gold element and approach the area using the cover and move bounding technique. Primary commo, medic and all heavy weapons remain with the cover element and move from one team to the other as the other team bounds.
Once the teams get into distance, the designated entry element approaches the convenience store. This is not done in a dynamic fashion! We have already reconned the area, and our sniper should have eyes on the convenience store to ensure that no threats have emerged. We aren't expecting contact, but we maintain tactical integrity in case there is a hidden danger. If some thread emerges, sierra can engage while the cover element lays down suppressive fire until the entry element can exfil. We then use rolling thunder to egress the area.
I should note that normally, no contact is made. However, OUR MISSION ISN'T OVER. While we are in the convienence store, we take every opportunity for civil affairs/psyops operations, buying candy or maybe cheap toys for the kids in the store or in the surrounding area. Even small seeds such as these can bear much fruite later.
As always, your tactical operations plan must be modified to suit the mission requirements, but I suggest these plans are far more tactically sound than flashbanging the aisles of the convenience store two times a day. Sure, explosives are fun and quick, but there are others ways to tactically enter a convenience store without resorting the the silly putty and bangers.
