I may not fully agree with hogdogs' terminology, nor his personal design standards; but, I concur with his general observation that birdshot is often underestimated. Hanging the messenger doesn't change the message.

I don't know about the building standards recognized by others; but, throughout the US, gypsum board (gyp bd) sheathed stud walls and partitions are considered real.There's no way a load of birdshot is going through a real interior wall.
Veneer comes in two types; anchored and adhered. They can range from thin water resistive or decorative wainscoting to massive full coverage stone panels. Yes, there are veneers that will significantly factor into the ballistic equation. The use of a plaster scratch coat as a veneer is unusual. Typically in veneer plaster (synthetic stucco), a proprietary finish coat is applied directly to structural or insulating wall panels. Closed cell panels have been used with some success. Systems incorporating exterior gyp panels have been subjects of litigation.I never thought of veneer as robust, but I suppose it is when compared to vinyl or aluminum siding. Stucco isn't too bad if it's the real thing and not just a superficial scratch coat for looks.an exterior wall with a robust exterior veneer like brick or thick stucco.
Not necessarily... In addition to being used in fire resistive assemblies, 5/8-inch thick gyp bd is often used when truer surfaces are desired, like in ceilings with 24-inch truss (or ceiling joist) spacing. And, also for their structural, thermal and/or acoustic properties. Not all 5/8-inch gyp bd is approved for fire rated assemblies, but you won't find it at your home center. If you've hung standard 1/2-inch gyp bd and 5/8 fire code gyp bd, you've probably noted the reinforcing fibers added to the fire code variety. If your experiences are limited to single family dwellings (SFD), then you may be unaware of the requirements for fire resistive construction well beyond the typical dwelling/garage common wall. When it comes to building codes, SFD's have the fewest restrictions.Walls pretty much everywhere in the US made with drywall is 1/2 inch. The only time you use 5/8 inch is in commercial buildings and the wall on your garage to house, cause it is considered a firewall. Code is 1/2 inch otherwise.
and, I'm guessing, no integral reinforcing steel, no significant lateral resistance. Also, a 14-inch brick wall is seldom solid, they are typically constructed in two wythes with a cavity between. Starting in the early 1800's, masonry cavity walls have been used for protection against moisture penetration. A 6-inch cavity is typical in a 14-inch brick wall.My exterior walls are 14 inches of solid brick from the basement floor to above the roof line - no wood, no cinderblocks, no insulation.
