## Key points

- Search the 13th floor and rooftop at La Grand Vie.
- Check floor loot as well as containers.
- Use stealth to avoid nearby commanders.

## Summary

High-tenacity fibers are a sought-after crafting material in Modern Warfare 4’s DMZ mode, used for several FOB upgrades. The uncommon ingredient printing upgrade is especially useful because it lets players manufacture higher-rarity crafting materials.

The recommended place to search is the La Grand Vie rooftop in Songdo Wharf, checking both the 13th floor and rooftop, including floor loot outside containers. The area has fewer enemies than the Chang-san Air Base armory and barracks, though commanders may patrol nearby; a silenced weapon and stealth can help avoid alerting them. The nearby Netshin Tech Complex is also a location for a chapter transmitter objective.
