This happened to me twice last night.
An operative threw a sticky bomb onto me, I died from gunfire, and the redeployment counter happened to spit me back out into the game as the sticky bomb was meant to explode on my corpse.
I heard the explosion, the screen had the damage splash redness, and I respawned with almost no health left. The extra health pip from one of my perks is what saved me.
The first time this happened I had remained in the ‘down’ view of my body, the second time I had been snuffed out, unable to be revived, and was waiting in the spectate-teammembers view until respawn.
The second one didn’t do as much damage on my respawn, but I still started with the need to reheal and the obvious loss of the bonus health pips I had at the point in the battle (command post upgrade).
