Knife/Battlefield 2142

The BJ-2 Combat Knife is an all kit weapon featured in Battlefield 2142. It functions identically to the knife in Battlefield 2, killing with a single hit with a very small range, but it now awards the player with the victim's dog tags upon a successful kill.

After fifty kills with the knife, the player earns the Dogtagger Dagger, a knife replacement with a set of dog tags attached to the hilt. The weapon is a cosmetic replacement, and functions identically to the BJ-2.
