You can get a Mossberg 500 for under $400 on a good day, and an AR for as little as $650.
10 ARs at $650 is $6500,
10 Mossbergs at $500 is 5,000,
7 magazines per rifle x 10 rifles at $16/mag = $1120
210 5.56 rounds for shift carry (standard military combat load) x 10 rifles @ .35/round = $700
50 buck shot or slug shells for shift carry X 10 shot guns @ $1 per shell = $500
1000 5.56 for training (far more than most military units get per service member) x 10 rifles @ .35 cents/round = $3500
500 buck shot or slug shells for training x 10 shotguns @ $1/shell = $5000

So using average market value, DLNR should be able to fund what they need for less than $25,000. Keep in mind that this does not include govermental discounts that most manufacturers provide to government agencies and/or state governments, which could easily drop that total below $20,000, and that is being extremely conservative.
Tell me again why the DLNR needs almost $60,000 or 3x the amount of money to get what they need?
