User blog comment:Darkman 4/What secondary types do you like to pair with your primary weapon?/@comment-1373755-20100504213149

SMG: Machine Pistol (M93 to be specific, it's surprisingly good at medium-long range)

Assault Rifle: Shotgun

LMG: Launcher, in most of my LMG setups, the LMG is just a backup for chipping away at a vehicle if the rocket misses.

Sniper: Shotgun or Machine Pistol depending on what I feel like using.

Riot Shield: Machine Pistol, but I rarely use Riot Shields
