A player who plays a medic in the
Battlefield series who instantly revives his teammates at
inappropriate times (e.g. when there are still enemies near them), causing them to most probably die again very soon afterwards, which will have a negative impact on the revived soldier's KDR (for as far as they care about that).
A medic typically performs Rambo revives when he is a n00b just to get lots of points or does it
for the lulz when he is a troll who likes to fck his teammates.
The "Rambo" part comes from the typical Rambo-style dash into groups of enemies just to get points for reviving teammates lying there. However, unlike Rambo, it is very likely that they both die in a matter of seconds.
