Yep. Standing or crouch, you're dead. But prone, you're underneath the blast radius. If you can get prone at the second you hear that buzzing/whirring sound, you'll survive. But it's damn tough to do.
But remember, Stalker Pro delays the trigger on betties/claymores, and it's a really ******** long delay. I was playing Seatown last night, and I saw a dude crawling up a ladder, so I threw a betty at the top of the ladder. But he had Stalker Pro, so he stood right on top of it for like 2 seconds, and wandered off. It exploded a full second later. Super long delay.
