Projectile weapon in the hands of Athan.
An MK-34 was a projectile weapon used in the 21st century.
The founders of the Terra Nova colony had weapons resembling MK-34s when they founded the colony in 2078. In 2151, the descendants of the colony were still using the weapons – Athan used one, but Lt. Malcolm Reed wasn't sure if it was an older model MK-33 or an MK-34. (ENT: "Terra Nova")
