Diret fires needs more teeth than 25mm and 40mm AGL.

How about?

NOTES
The producer of the LAHAT gun-launch ATGM (pg 6-58) offers to produce a version for use in the M40 launcher. The tandem ATGM is a viable threat to all modern armored vehicles. Use requires a tripod-mounted laser guidance unit, as used with MT-12 and 2A45M AT guns.
The rifle produces a massive amount of noise and smoke which reveals its location. Thus a first round hit is critical.

This all assumes the idea of the project having both a huge body of skilled and experienced soldiers and a huge body of high quality, hi tech military gear.

I'm not sure that was ever the case. In Desert Search they point out the project didn't even have night vision for its TOW launchers. MARS teams rarely seem to be more than 3 or so vehicles and maybe 20 people.

This is suggesting that once you include support and maintenance staff the Project had something like 10% of its MARS teams just defending Prime base. That's before you even get into the space required for garaging the vehicles, bunkering the troops and storing the ammo.

Even then assuming the threat level the project was up against; Warsaw Pact invaders, rogue battalions of the army, thousands of refugees then even a couple of dozen light armoured vehicles wouldn't have made much difference.
This might be enough to defend an airfield in a war zone, but even then that's assuming you've got a lot of cavalries to come over the hill if really needed.

More likely I'm guessing Prime's security would rely on the following.

1 Not being seen the Project got pretty good at hiding its resources.
2 Automated defences, again the various scenarios suggest a preference for robotic style gun emplacements, smart mine fields etc.
3 A completely separate security force and the kicker is probably not knowing what they were defending.

The project seemed to have great strengths in both ruthlesness and secrecy in a noble aim.

NP-5 has two basic missions;

1. To set up a security screen that filters refugees (disarming the heavily armed ones at least) and then directing them to a refugee camp setup some 150 miles to the northeast. This is the mission brief as explained to the rank and file.

2. Only two members of the team (the CO and XO) are aware that NP-5's main mission is to screen a secret base in the area. They do not know the exact location. They are aware that they must monitor a special frequency for additional orders, but have no means of contacting the base.

Look at the "Warhead Data" thread or the "Soviet Weapons" thread. I have done stats on other equipment like the 90mm RR..... Umm and the KFS Refit thread too.

I'm meaning to download, copy those. I'm pouring over Kephart's camping books for TL E-D camping gear for Texas and the American Outback. The P17/M30 Express, M1917 and M1911 Commercial, Early Match BBQ guns are the closest to that I've done lately.

Bunkers present an interesting paradox in that they are simultaneously the toughest and most vulnerable sites most forces have.

You can't pack them full of mouseholes to sally or sneak out of. Firstly because a bunker maybe behind hundreds of feet of granite or rebarred concrete that stuff is hard to dig through and if you dig enough holes you're also going to compromise the integrity of the whole structure.

Not to mention any tunnel wide enough for a man to crawl through to get to the door, will allow somebody else to sneak back through. The doors however tough they are will stuff need to be able to move and thus will have weak spots such as hinges.

Even if you were to come up with a truly impregnable fortress, then the kind of foes the Project were planning on would simply think,
"hmm suspicious lets drop a largish nuke just to be sure."

The trick would be to come up with a base that was both as bomb proof as possible, as life proof (e.g. people could live in it for decades with no contact with the outside world), defensible in a pinch and completely secret. Pretty tall order.

As such I suspect the project would build a tough underground structure with automated defences.

But at the same time would try and keep people away by "Scooby Dooing it"
Creating an atmosphere that would keep meddling kids away.

The easiest way would be set off a very small nuclear device the bunker could survive.

Then maybe put together a security team designed to look like a terrifying gang of marauders.

Or release zoo animals and put up signs indicating they were escapees from eccentric animal owning billionaire who couldn't take care of them after civilisation ended.

The trick being to have a simultaneously impenetrable and uninteresting base.
