US AFV's use 66m smoke grenade dischargers which have to be manually fired. They launch the 66mm L8A1 Red Phosporus grenade, which is a thermal smoke grenade, designed to defeat or at least degrade thermal imaging. The M1 series tank uses two 6 tube M250 launchers - one on either side of the turret. The M2/M3 Bradley IFV, USMC LAV-25, the Stryker family of vehicles, M113A3 all use the 4 barrel M257 launcher. I'm not sure of the incindiary effect of the L8A1's vs. troops, but I've been told they can start fires.
