You know, I really should look at my own web pages:

Belgian NR-413 Stake Mine: 2kg pressure on the tripwire
Belgian PRB M-966: 1kg pressure if a tripwire is used, 4.5 kg if pressure-detonated
Bulgarian PSM-1: 1 kg with a tripwire, or 8 kg with pressure
Chinese Portable Bounding APERS Mine: 1.5kg on the tripwire
Chinese SAPEM: 2 kg of pressure
Chinese Type 69: 1.5kg on a tripwire or 7 kg of pressure
Czech PP Mi-Sr: 3 kg of pressure
Egyptian Bounding APERS: 2 kg on a tripwire
Russian POMZ-2: 1kg on a tripwire
US M-16A1/A2: 3.6 kg on a tripwire or pressure

These are just the "light-touch" mines I found on my own site; I should trust my own research (and keep better track of what's on my own site). Note also that the typical tripwire-triggered mine is set for 5-8 kg of pressure, which is also not really that much. (I still don't think a rat is likely to set off any but the lightest of tripwires -- maybe in the 1-2 kg range at best, and he just might be likely to walk right under a tripwire without triggering it. Do they train those rats to recognize tripwires?)
