Marks, colour, type — and the files.
Everything needed to show the group correctly, so nobody has to redraw a logo from a screenshot. All marks are unregistered trade marks (™) of the sole trader named in the Impressum.
The arch.
The Bunker Corporation mark is a single angular arch — a bunker entrance seen head-on. It is the one mark that stands for the group as a whole. It is always shown in one flat colour, white on the dark ground or black on a light one, and never with a gradient, an outline, a shadow or a container.
Clear space: keep a margin of at least half the mark's height on every side. Minimum size: 24 px tall on screen, 6 mm in print; below that use the square icon.

Set in type, not drawn.
"Bunker Corporation" is typeset, never a logo file: Space Grotesk Bold, upper case, tracked +8 %. Beside the mark it sits at the mark's cap height; below the mark it is centred and stacked on two lines. It is followed by ™ on its first use on a page and not afterwards.
Never "Bunker Corp.", "Bunker Corporation Inc.", "GmbH" or any other legal suffix — the name is a brand, and adding a legal form to it would be a false statement about the entity.

Each division has its own.
Division marks are shown at a common height, never a common width, and they are never swapped for one another or for the group mark. A division's site leads with its own mark and names the parent in its footer; the group site leads with the arch and shows the division marks only where the divisions are listed.

Three grounds, three inks, one emissive.
Depth comes from stacked near-blacks, not from borders everywhere. The emissive cyan is hardware, not wash: it appears as a rule, a focus ring, a hover state or the glow behind a mark, and it never fills a panel or tints body text. The quietest ink still measures 5.9:1 on the ground — above the 4.5:1 body-text minimum of WCAG 2.2.
Three faces, self-hosted.

The short list.
- Recolour, outline, rotate, skew or add effects to any mark.
- Place the arch inside a circle, badge or rounded tile. The square icon is the only container.
- Put a division mark where the group mark belongs, or the reverse.
- Add a legal suffix to any brand name, or use ® on any of them.
- Describe Bunker Corporation as a corporation, company group or holding. It is a brand of a sole trader.
- Present a "coming soon" brand as a shipping product.
