Close-quarter fluid snaps - or C-KAFS - are a nasty reality of warfare in the frontier or otherwise. Seasoned vets are all too familiar with the deceivingly benign hiss and snap that signals one thing: get out and get low. C-KAFS were improvised from mining equipment during the Freight Wars. They're extremely dangerous to fabricate, but all the materials are readily available at any subsurface mining operation. Set on a timer, detonated remotely, or slung from afar, when C-KAFS snap off, they first inundate the area with a thick vapor (the hiss) that acts as a substrate for a deadly seismic wave (the snap) to pulse through. Any enclosed membrane (eye balls, organs, arteries) within the vapor cloud are at risk of rupture. The introduction of Tovoka Rainment's TR506P Impact Sheath greatly reduced the lethality of the C-KAFS that plagued those frontier hot spots. The flexible sheath tiles absorb and neutralize the bulk of the seismic blast, allowing the wearer to focus on the objective at hand. The only downside? The weight. Mercs groan when contracts take them into C-KAFS territory, but you'll never find a combat vet without the Grounder Pounder on hand, not a live one anyways.
