IRON NEST Ammunition Guide: Choose the Right Shell

Even an accurate firing solution can fail if the selected shell is unsuitable for the target. Read the intelligence first, choose the ammunition family second, then calculate and load.

Confirmed ammunition roles

• Armor-piercing (AP) is the confirmed anti-armor option.
• Smoke is a battlefield-control round rather than a direct-damage option.
• Phosgene gas appears in the official store description as a specialist chemical option.
• Star shell is unlocked and used in current full-release footage for illumination-related tasks.
• Incendiary shell is purchased and used in full-release footage.

A safe selection routine

1. Read the target report and note any stated armor, structural, visibility, or observation requirements.
2. Select a shell whose confirmed role fits that report.
3. Re-run the ballistic calculation after changing ammunition or propellant charge.
4. Confirm the loaded shell and propellant charge before firing.

What “30 ammo types and abilities” means

The official wording combines ammunition types and abilities into one total. It does not verify 30 distinct shell types. This guide therefore avoids presenting a fabricated 30-shell table.

Unlocking and requisition

Full-release footage shows ammunition being unlocked or acquired with requisition. Availability changes with progression, so the correct practical question is not only “what is best?” but also “what is available in this operation?”
