Regarding "gear":
1) My Brain
2) My sidearm in a shoulder rig: Ruger .357 magnum 4" revolver
3) 2 pr of handcuffs
4) Badge
5) Flashlight (small one, uses 3 triple "a" batteries, 7 lcd halogen bulbs, size of a roll of qtrs. Fits nicely in the palm of my fist...just like a roll of qtrs...
Alt. gear depending on criminal history: Blackjack, retractable baton, back up gun, chemical agent, threat level 3a exterior BP vest with front and rear trauma plates ( manufacturer guaranteed to stop 5- 7.62x39 rounds), extra cuffs, leg shackles, belly chains, spare flashlight, binoculars, rubber gloves, extra ammunition (500rds), extra speedloaders, weapons cleaning kit, shaving kit, change of clothes, foul weather gear, camo poncho with liner (great for rural/woods surveillance), toilet paper (you neer know when mother nature willc all you), liquid waterless soap, bottled water, ...that's about it.
All of this stuff I keep in a "Jump bag". I change the clothing out once a week, and I normally stick a dryer sheet like bounce or febreeze in the bag to keep the clothes from stinking. I also stick one in between my vest flaps, helps to eliminate odors, esp in the summer time when sweat and stuff builds up. The shell can be washed, but not the actual panels themselves.
Oh and don't ever forget the ever useful duct tape. I think that about covers it.
Did I miss anything ?
