NETWORK NOW WITH YOUR NEIGHBORS!
Make them come to you. Time is on your side. You have food, water, shelter.
Prepare yourself psychologically for loses.
Never allow the opponent to gain control of the situation. He may have temporary tactical superiority, but you have the advantage of knowing what is available to you because you have planned. Read the story of Elfago Baca for an interesting idea. This is ideal if you're on a hill or rise and do not have to worry about flooding during rains.
Wound as many opponents as possible to eat up their resources and sow fear and doubt. You can always kill them later.
If you are able to capture one of your opponents, take the opportunity to make sure the compatriots of the individual can hear his/her screams. This may provoke an unthinking emotional response from a lover, friend or family member thus exposing their position and possible positions of others. This is no time to be "civilized".
If you can't get a response, kill and "cook" a portion of the individual and "share" it with your attackers. Wrap it up, attach a note, and toss it out a window. Use psychological warfare tactics.
A grenade in the dark is always fun. Especially if they've already encountered some of your booby traps. Keep them off balance and guessing.
Allow no survivors. Take no prisoners. No exceptions. NO EXCEPTIONS! You can't watch them 24/7. You can't trust them. Again, this is no time to be civilized!
Be prepared to deal with the emotional effects of the incident on your party afterwards. This is when you will be extremely vulnerable and you need to have prepared people ahead of time for the possibility of raiders and the outcome of the raid.
