I was kinda able to cheese it, I was killed, then reinforced. I managed to land on a big rock near a base, and the Charger was just stationary underneath me waiting for me to move, and easy target for a resupply pod! Wasn't even aware there was an achievement for it.
I suspect you could also do it from range with some luck, or by utilising the stun grenades.
Good thinking the stasis field things would make it easier as well.
