yea, basically how we do our acre server is this....
start ARMA with all acre stuff enabled. go to the editor and toss a couple acre boxes down. You can also set each unit, if you feel so inclined, with a set radio.
i.e.
this addItem "ACRE_PRC119"; this assignItem "ACRE_PRC119";
or
this addItem "ACRE_PRC148"; this assignItem "ACRE_PRC148";
but you will have to enter either of those lines into each unit as you see fit.
Lastly, you will want to throw down a few radio towers around the island. Otherwise you will loose coms easily.
