Hot Spot #1: a Mk. 82 Snake-Eye bomb (a dud) that didn't explode and was marked by EOD for disposal (note the sign showing a "bomb site #1").
Hot Spot #2: a piece for a market place. Prices are low (note the "2") at the moment :-)
Hot Spot #3: Another random piece that could be placed in any backyard on the table. Again I used a sign showing a price to hide the "3".
Hot Spot #4: This one is rather funny marker. It shall show the fourth of my markers. I thought it would be pretty hilarious to mix the word "formula" (a term used in a lot of engine oil commercials) with "mullah" (a word common in the middle east) - and ended up with "4-mulla oil").
