Today, it's modern US police. First 3 pics are patrol officers and their rides. These officers are all Crooked Dice 28mm. Great figs. 5 packs, 4 figs each. One pack each armed with pistols, shotguns, patrol rifles, batons, and bolt action rifles (SMLE's though - an odd choice for US police...). Each pack comes with enough heads to outfit each officer with either traditional "bus-driver" hats, "Smoky-the-Bear" hats, baseball caps, or bare heads. Even female officers are included. These are great figs! Vehicles are 1/43 PD cars (just a bit big, but they work for us...) Anyhoo, I have done 3 different generic departments, as our "cops-n-robbers" games will be set in a small town somewhere, and that will involve multiple departments responding through mutual aid.
The next 2 pics are the County's SWAT team. They are older Steve Jackson Games Special Ops figs, but they work out quite nicely for a SWAT team. Outfitted just right - a leader, a breacher with a ram, a sniper, and 3 team members. All but the breacher and sniper are armed with H&K MP5s. The breacher has a shotgun slung on his back, and the sniper has (Surprise!) a scoped rifle. One of the MP5-armed team-members has a flash-bang grenade readied. These figs are OK, sculpt-wise, but they painted up decently enough.
The vehicle is a Solido Cadillac-Gage V100, kitted out in Police livery (I plan to doll it up just a bit).
Enjoy!
