Rack Notes
How to Read the Rack
The short code is the compact identifier shown alongside each full shell name. Search either form: STAR finds STAR Shell, while Smoke is better found through its in-game code, SMK.
One entry intentionally preserves a visible naming difference: the abbreviation is PLCM, while the display name is PCLM Shell. Both forms are retained as shown rather than silently standardized.
The rack is an identity and purpose reference. It does not turn shell names into presets or imply that one entry is the right choice for a particular encounter.

The rack includes 21 shell identities, each paired with the abbreviation shown for it in the current checked set.
Use the search field at the top of the rack. Enter the short code or part of the displayed shell name, and the matching cards will remain visible.
No. This page is for matching shell identities to concise purpose summaries. Use it to understand what an entry represents, not as a table of combat outcomes or encounter-specific choices.
EMPTY Shell is present as a verified identity, but no verified purpose text accompanies it. The card therefore identifies the entry without assigning it a function.
They represent two visible fields for the same entry: PLCM is the abbreviation and PCLM Shell is the displayed name. The rack preserves both forms exactly so players can recognize what they see.

Shell names, abbreviations, and the meaning behind available in-game descriptions were checked against the current game build. The summaries on this page are independently written for quick reference. IRON NEST Field Manual is an unofficial resource and does not present this rack as an official game database.
