Image Description: The ARC-16s utilize strategic explosives in many instances. Often time, entrances to underground Yhe hives need to be sealed, or pathways and various terrain needs to be booby trapped. This compact explosive has proved effective in caving in tunnel entrances, as well as eliminating any pursuers in the blast. It can be detonated remotely and set to motion detection.
On the left side of the backpack is a container of Nashiri Needle Wire. The Nashiri were space pirates that gave up on their chance to join the Greater Good. All that remains now of their people are a few salvaged pieces of technology. One of which is the Needle Wire.
Needle Wire is sharp on a molecular level. The wire is usually attached across a door frame to discourage any pursuers. The thin wire is virtually invisible unless one knew what to look for. Anyone running quickly through the doorway would be in for a nasty surprise. Needle Wire is so sharp that it can cut through most limbs with relative ease. Armor can be a protection, but the wire is capable of cutting through to a degree.
This technology is perfect for covering your back, but would of course need to be marked with a nav point so no squad runs into it by accident. Any Tau forced to clear out a Yhe infested building or ship has been saved many times by this silent killer.
