I don't know if either I'm not pressing the right button for this weapon, but in the game you can throw them... They were made so you can go up on a tank and place it on the armor and then ignite the fuse.
In game, I thought the "fire" button would do this when next to a tank... little did I realize my avatar threw the charge and it blew up killing me and the tank.
I hope they fix this, as to be accurate about having to actually place this charge on the tank. That's what the magnetic pincers are for, and that's why its a hollow charge, to place on the tank for maximum penetration, not a throwing charge like the 3kg satchel or the geballte landung.
