What About Those Tanks?

What About Those Tanks? is an achievement in Halo: The Master Chief Collection. This achievement is obtained by destroying seven Type-26 Wraiths on the mission ONI Alpha Site.

Method
Players can enable campaign scoring to help verify Wraiths are being destroyed.

Even on the higher difficulties (Heroic or Legendary), only a maximum of six Wraiths will spawn: four at the bridge and two in the inner courtyard. Thus, players need to restart the level at least once.

After destroying the bridge, four Wraiths would have spawned at the other end of the bridge. Occasionally, one may have advanced closer and blown up with the bridge. Use the M6 Spartan Laser to destroy the Wraiths. If the laser runs out of ammo, the player can also use the stationary M68 Gauss cannons located on either side of the entrance into ONI Alpha Site. Since the lighting of the level actually lowers visibility when in VISR Mode, the screen panel on the controls of the Gauss cannon can be used to locate the Wraiths (marked red on the screen) on the other side of the bridge.

Restart the level as many times as necessary to destroy seven Wraiths. The achievement will be awarded upon the destruction of the seventh Wraith.

Trivia

 * The name of the achievement is a misquote of Dutch's dialogue in the opening cinematic of the level. In actuality, he asks, "What about those Wraiths?"
 * The requirement of destroying seven Wraiths is likely a seven reference.
