Go to the Trading Post here on AWRM. Lord Eron has web belts, canteens, canteen pouches, 1st Aid/Compass pouches and tons of Y suspenders. all for cheap! Then find yourself a very good butt pack, either USGI Canvas Vietnam era or modern version with fastex buckles. Wal Mart (here I go again..and I hate it too..lol) has the following gear I would suggest. I checked it over at work.
Silva compass :$10.84
Water treatment tabs: $6.26
Spork :$2.44
Candle lantern :$16.46
Candles for above (use without ltn. too):$2.44/3
Match Case :$.96
Wet Ones Outdoor wipes (hygine):$4.24/35 wipes
Keychain led light for survival kit:$3.48
Essential Waitpack black :$6.46
(not the same as a butt pack/harness, but in a pinch or as a backup/accessory..kill the reflective strip).
H2o Proof box (fits inside above pack):$9.84/LG
$$6.46/SM
Hardware dept. sells Brown, Black and White Duck Brand Ducktape! Sorry no OD. If you know how to mend, then the fabrics dept has upholstery thread in black an needles/pins ans small snips for field repairs.
You can also get a 1ST Aid kit for around $10 there too. I know this is not true military, but I do use some of these items myself and would not recomend things I do not use. In a pinch and you seem like you are, these ideas will work...Send me a list of what you need.. I will try to help you out. Private mail me.
