Probleme Assigment Unit - Explosives Expert

It says: Make Multi-Kills of 2 or more using Explosives

I killed 2 in a tank with C-4 Explosives, it did not count.

I killed 2 in a tank with a RGP anit tank man pad, but it did not count either?

So what does count? Only granades? Mulit Exlosive Lunchers? I dont get it!

Or is that just a BUG again.

I still wait for my spawn beacon, which I unlocked via the assignmet, but still cant equip it!

Please help!

On a personal note, getting skins and important equipment via assigments is a VERY BAD tool, imo!
