OK well, first thing you need is protection for your face. Thats either a paintball mask or ballistic goggles. Thats the most important piece if kit you have. Protect your eyes. Don't worry about anything else until you can do that, it doesn't matter whether you buy or borrow. Now once thats taken care of that you need good boots. These are also not an option. Good boots protect yout feet and ankles from all the abuse that the environment will dish out. Running shoes are not good enough, nor are steel toes. Both will destroy your feet. You don't need camo yet, although it would help. Green clothing will be ok, or failing that neutral tones. Besides that, weather appropriate clothing to stay warm and dry, extra socks, and water and something to carry it in. And food, bring a decent lunch as well as a snack.
