- 25mm models need updating to 30mm
- Cavalry on outdated rectangular bases

Notes · Q & A
What does a formation such as 7 × 5 mean
It means seven positions wide and five positions deep, for a total of 35 positions. Always confirm the listed base fit as the same formation can be available for different base formats.
How do I choose the right movement tray
Match the tray to the shape and size of the bases you are using, then choose the formation you need. Check the selected product's drawing and specifications for base fit and overall tray footprint; do not choose by model count alon
How should I use the technical drawing?
Choose your option first, then use the technical drawing and Technical Specifications to check the physical dimensions of the product. When matching an existing part or accessory, use the drawing rather than relying on the product name alone.
Can I rely on the nominal size alone?
No. Products with similar nominal sizes can have different physical dimensions or fit differently across brands and systems. Check the technical drawing, specifications and any product-specific compatibility note before ordering.
