Bushmaster versus RARDEN on the Warrior IFV

Would a stabilized 25 mm Bushmaster make Warrior a more effective infantry fighting vehicle than its 30 mm RARDEN?

The Bushmaster is said to have performed better in most trials, but RARDEN retained an advantage near nuclear detonations and the gun change would have limited effect on Warrior's missile-supported role.

The 25 mm Bushmaster and 30 mm RARDEN are judged broadly comparable for the British vehicle's intended work. Trials are said to favor the Bushmaster in most circumstances outside nuclear, biological, or chemical conditions; the specific RARDEN advantage discussed is its mechanically powered operation when a nuclear weapon detonates nearby. Warrior's most demanding anti-armor targets are handled by MILAN rather than by the cannon alone. That limits how much a stabilized 25 mm gun changes the vehicle's battlefield role. The later cancellation of a 40 mm upgrade is criticized, and the discussion considers whether a larger weapon could extend the vehicle's useful life.
