Ammunition is a scarce commodity. However, using the right
bullet for the job helps. Use the small arms for the in your
face bug work. Save the missiles, grenades, and nukes for the
bug holes and Tankers. Heavy nerve gas is a gutsy way to ruin a bug hole's day.
Make sure that you have a squad covering the poor soul hoping
to drop the gas down the hole. Ambush Arachnids whenever possible. Use three squads to form
a U. Run a couple of Mobile Infantry under the bug's nose and
lead it back to your trap. Rinse and repeat for the large bug
swarms.
