How sure
Which Commander drops what is the game's own hint, and several guides agree. The X01 recipes match across two guides. No guide has drop rates, and no drop is guaranteed.

Short answer

Each one comes off a Commander. Colossus drops Military Composites, Deathstalker drops the Prototype RF Module, the NK Battle Tank drops Nano-Structured Alloy, and Experimental Compounds turn up now and then. Since Season 1 you can also print all four inside X01, each from 2 Epics and 5 Rares.

Which Commander drops what

LegendaryWhere it comes fromPrint it at X01
Military CompositesColossus2 Nylon Laminate + 5 Nylon Cloth
Prototype RF ModuleDeathstalker: loot the Helicopter Piece containers on the wreck2 Power Regulator + 5 CPU
Nano-Structured AlloyThe NK Battle Tank2 Turned Components + 5 Structural Alloy
Experimental CompoundsCommanders, now and then2 Volatile Explosives + 5 Binding Catalyst

Guides split on Experimental Compounds. Game Rant and COD Central say it drops from Commanders at random, without naming one; DMZTracker files it under Colossus. COD Central's writer also found one lying on the road at Imjin Farmland.

The Bosses page has where each Commander spawns and how to take it down.

Kill it, then get out

  • Nothing is guaranteed. No guide we checked says any Commander always drops its Legendary. DMZ Codex lists RF Module and Biomaterials as examples from a Deathstalker wreck, not a fixed drop.
  • It only counts once you extract. Put it in a Secure slot right away. What's in a backpack's Secure slots survives a failed exfil.
  • Expect company. A Commander fight is loud, and exfil sites draw ambushes. Plan your way out before the kill.

Or print them at X01

Season 1 (Nov 5) added the X01 facility, with a 3D Printer inside that turns Epics into Legendaries. It's the way to get one without a Commander fight.

  • Getting in: an abandoned elevator in square B0, north of the Political Prison, no key needed (DMZMap). X01 runs a toxic gas timer of about 20 minutes, then a 5-minute shutdown.
  • Finding the printer: head for Production Assembly and work the west side. Guides describe the last stretch differently: Game Rant has a west-side ladder down to the north area, while DMZMap and MMOEXP put it in an upstairs office.
  • Bring the ingredients in your backpack. The printer works from what you carry, and these recipes only work inside X01.

Each print takes 2 of one Epic plus 5 of one Rare. The Epic materials tutorial covers where to find the Epics and how to unlock printing them back at the FOB.

Loot or print?

  • Print when you already hold the Epics. It skips the Commander fight, and X01's timer is your only clock.
  • Loot when you're going after that Commander anyway, or you're short on Epics. Two Epics plus five Rares is a lot to carry in.
  • Military Composites is the one to print first if you haven't unlocked Epic Ingredient Printing yet: it needs 5 Composites, so printing them is a way in without Colossus. Five takes 10 Nylon Laminate and 25 Nylon Cloth (our arithmetic from the recipe).

What they're for

LegendaryWhat uses it
Military CompositesEpic Ingredient Printing (5), Tempered Armor Vest (2), Secure Scavenger Backpack (2)
Prototype RF ModuleVendor Item Upgrade I (2), Large Secure Backpack (2), Crossfire (2), Fulton Drop Marker (1)
Nano-Structured Alloy3-Plate Helmet Armor Vest (2)
Experimental Compounds3-Plate Ballistic Gel Vest (2), Door Breacher Charge (1)

Counts are from Gaming ProMax's recipe list.

Prestige needs them too. The official FOB guide says your third Prestige and every one after it costs four Legendary 3D Printer ingredients, along with a Legendary Plate Carrier and Backpack. Save your spares.
