This sounds like you want a single shot swarm for your merc so thats a big no . You either go anti infantry and hope someone in your team is anti vehicle or speck into anti vehicle yourself .. simples. You cant have the best of both worlds.

Yeah... No. The problem with this is that it'll mean everyone would have anti-tank capability, this would mean the utter extinction of dedicated vehicle pilots. It's horrible enough for vehicles users with the one or two very dangerous AV users you'll run into in most matches, add in every AR scrub carrying an AV weapon with good range, LAV's will die, dropships will die, tanks will die. If you want to kill high level vehicles, you should skill into high level AV.

If yoir looking for a corp then give us a shout and youll understand better why there is no middle ground personally av nades do the job when im running anti infantry

It would be nice to have the ability to carry a single-shot anti-vehicle weapon like a LAW. To prevent it from being used as an anti-infantry splash damage weapon, it could assume shaped-charge properties so it only does big damage to the point of impact. Using only a swarm launcher is really limiting as you have to give up a decent primary. Maybe if the LAW occupied the sidearm slot, that would be cool. Too many times, i feel like a british paratrooper during operation market garden or tom hanks at the end of saving private ryan. I think having a middle ground on anti-tank capability would be a good balance against tanks. Note, inam not suggesting the LAW to be a one shot killer but to do some decent damage and make tankers think twice before running around without infantry support. i find the av grenades to be impractical.
