Your options are a missile launcher with anti-personnel missiles, a heavy stubber, and a heavy bolter. Basically, do you want to shoot missiles at bad guys, bullets at bad guys, or missile-bullets?

The missile launcher is the most powerful and longest range, but has 5 rounds and weighs a lot. The Heavy Bolter is heavier, packs a smaller punch per round but can fire many more shots. The Heavy Stubber is the lightest of the three, has the highest rate of fire, but is also the weakest and shortest ranged while still suffering from the bracing problem of the Bolter.

The heavy stubber also benefits from having the most easily acquired ammunition of the three.
