The key to creative problem solving is knowing your resources.
Being in Afghanistan you have ready access to "SPENT" ammo casings. DO NOT USE LIVE AMMO.
A single 7.62X51 Nato (aka .308)
A 5.56X45 Nato (aka .223) capped by one of the following,
9mm
40 S&W
45 acp
Any of the above will give you a working approximation of a AA length dummy.
Wrap with duct tape, band aids, rubber bands, scotch tape, medical tape, zip ties, plastic wrap, MRE pouches, shoe strings, letters from home, anything non-conductive to protective your dummy from grounding out in the flashlight.
Just leave the ends bare to complete the curcit.
If you use Brass cases your good to go.
If they're lacquered steel cases scrape or sand off the lacquer from the ends.
Good luck, keep safe & post your solution.
