Re: Use a sword
Actually no. Kill the healer first. Then you take out the ranged opposition with concentrated firepower, while avoiding the guys with axes and swords. These are usually the last guys to go, and must be turned into charred pincushions before dying, they are really tough.
Leaving the analogy, it applies to every war, which is why Geneva Convention exists to avoid the slaughter of Medics and Red Cross-tagged vehicles. Then you take out their long-range effectiveness, (usually the Air Force and Navy), and end up on infantry and MBTs.
