heck.. even a few well placed mounds of dirt would be good.

and sandbags.. even unfilled.. just having them ready to fill.

remember.. in an EOC situation.. be creative too. old field with a broken down barbwire fence is a fireing line just waiting to be scavanged. a few tposts and some stragly old barbwore, even laying on the ground is effective.

they either have to move slower across it and not get tangled.. or they have to go around it.

when they move slow over it.. you have them in a fireing line.

when they go around it.. you arrange the 'around it' into a fireing LANE... that way over or around.. you got them. IE.. give them 2 bad choices to make if they want to come see you...
