Smoke Dischargers, And Fragmentation Grenades Fired From These

[Suhiir]

One thing that really needs to be kept in mind is units have only four(4) weapon slots.
This imposes a number of constraints on what can be done.

Take for instance the average USMC Rifle Squad (13x men):
9x M16A4 Assault Rifle
0 to 3x M27 Infantry Automatic Rifle
0 to 3x M249 SAW
3x M203 40mm GL
1x M39 Enhanced Marksman Rifle
3 to 13+x AT4 LAAW
13+ M67 Fragmentation Grenade

So we have 7 distinct weapons and 4 slots.
Often you have to pick and choose what weapons a unit will use simply because the game cannot handle what it really uses.
