yeah five medics may be high, it was just a number I came up with off the top of my head. When I originally wrote the rules, it was lower, and then I changed them to rules for a paintball milsim event. I changed all the numbers because I anticipated that way more people would be there. Anyway none of those numbers are like set numbers, they could all be changed as none of them are probably right anyway.
EDIT** I will get a pic of the field from google maps.
