AT rifle grenade is reliable? Que puma driving up to my rifle squad; i activate rifle grenade in hopes to cripple it. The ability starts flashing, but my rifles sit there and do nothing. Eventually, puma drives around and escapes. My riflemen are still standing there doing nothing, and commanding them to move stops the "active" AT grenade. It constantly bugs out like this in many games. The vehicle is in range, but my rifles just dont do anything when i activate the ability. It looks so stupid when they sit around for 15 seconds like that.
I think the ability is canceled because the puma enters the minimal range bubble of the rifles about to shoot the AT grenade. Only reason I can think of that would cause the ability to be canceled. I have had this happen numerous times where an SC or Puma charges through my screen line of rifles to run down my M20 or Mortar HT.
