Making smoke pods for FA is very easy. Basically you'll want to make an inert weapon. By inert I mean non-moveable and non-destructible. You'll want to set all speeds to zero and set the maximum altitude to around 100K. Don't worry about range. Set all damages to zero and then set its removal to a value of about 1 or 2. Then in smoke effects, select the color smoke you want (black, grey, white, transparent) and set its frequency to something between 20 & 30. Then set its exist time in this window to about 4, existing in the air for 1 second. Make its start size small, below 10 and its end size above 35. Then go into firing info and make it hold many projectiles. Through the toolkit you can only set 255 but in the JT file itself you can go up to 32767. Make it have between 255 & 1000. Set all the other values to one except the last one, set that to zero. In ordinance parameters click loadable to hardpoint, continuous fire, and final collision check late. Then just save and you have a smoke pod.
