Tactical training in BC
I would go and have a chin wag with the owner of Panther Paintball. He owns a vast amount of land, has a LARGE collection of military vehicles and combat vehicles on private land.
He is also a member of the Canadian Historic Military Museum which incidentally used to occupy space at the old Chilliwack Base so he may have contacts and leads on plots.
The other option to consider is the Panther paintball field itself. It is already set up with cabins, varying terrain, quasi-urban combat areas, open areas and highly dense wooded areas. Running something mid-week might work out well considering weekends are reserved for gameplay.
This might be a good place to start
