If you are smart in a water fight, you won't just use water guns and water ballons. If you don't have enought people to guard your base you could use "Land- Mines". To make a land-mine, dig a little hole and stick a water ballon in it. Cover it with grass and when someone steps on it from the other team and DRENCHED! There are also ways to keep from getting wet. Get a box from a Super Soaker and make a small handle on the back and use it as a shield. Commmunicate with your team-mates. Mabye you are to far away, but what did they invent walkie-talkies for anyway?
If you want your team to win you more importantly want to be less wet than try to get the other team wet. Avoid traveling on open spots were there could be ambushes. Wear camaflauge out-fits so they don't see you. Never go to the other teams base alone. You might run out of water, so it's a good idea to cary a little 6' water-gun. Never go to raid a base with one water ballon, once you throw it your're out of ammo! So be care-ful out there. Remember it's better to stay dry then have them totally Drenched!
Tie a water ballon on both ends of a string. Lay the string on a branch and have one of the ballons higher [better if hidden] and one ballon lower. If the eneimes see this they will problay take the lower ballon, not knowing the higher ballon would be ther, pulling it of and the the higher ballon falls of and DRENCHED! them!
