    I think you should have several spider holes, he drops a grenade down the air shaft, you come up out of a spider hole and convince him that was a bad idea...

    Second - run several false air intakes and have several real intakes

    third - have the real intake go up through a fake outdoor toilet, wishing well, Cement wall, middle of a pond, stream, etc

    forth - make the intake have a dead drop that goes past the real shaft to the bunker

    fifth - have the ability to close them

    Sixth look at submarine technology...

    The first thing would be to hide the openings. I think the best and easiest way to do this might be to pile some big rocks over it, then cover this with dirt. Let's say a large rock to either side with a big flat rock for a roof, then dirt on top planted with grass, ferns, or whatever. A loose pile of rock has enough openings to allow air to flow, and you can make it look very natural.

    I would also do a screen of some sort to block critters. A second screen of heavy-duty wire cloth, placed more than an arm's length down the tube would stop anything dropped into the tube. Some of the other ideas already presented here, would also be handy. Not that sure about the practicality of the water-filled trap though.

    You should probably have some way of shutting off the air in case someone drops CS in the area, or in the case of an NBC type attack.

    You should plan to have multiple air shafts if possible.

    The best bunkers I have seen are made of 10' or 12' diameter corrugated pipe. This stuff is designed to be in ground contact and will last 100 years or more. You can see some of the details of their construction, including how they handle air intakes on this site (and associated videos)...

    ​one more thing that can be done,is any structures that are close enough for this.run the air vents up the wall(s) and through the roof of the above ground structures,where they appear to be a part of it..especially if the structure is a steel and tin building of some kind.chances are,no one will want to burn it..

    build a hole in the air vent at the bottom run your outside line at the bottom and the line going to the bunker at the top I recommend at least a 2ft all around hole deeper is better, extra protection. Then make your hole concrete around the air vent for a few feet with 2 filters (might as well make it gas proof or fit it for a gas filter). MAKE 2 of these complete that way the air will flow either way. Make a third smaller distant hole with a big dip at least with one filter that is closed off as a back up if something happens to your 2 mains, it will function to get bad air out.
    oh ya hide the openings
