What tactical advantage did the MG42's quick-change barrel system provide?
It allowed sustained fire without the weapon being disabled by overheating
It allowed firing two different calibres with the same barrel
It made the tripod unnecessary
It cut the weapon's total weight in half
A trained gunner could swap a red-hot barrel in just a few seconds, essential given its extreme rate of fire, which would otherwise overheat and damage the barrel quickly during sustained fire.

What feature did many units of the M26 Pershing's 90 mm gun have?
A muzzle brake visible at the end of the barrel
A short howitzer-type barrel
A double barrel mounted in parallel

Schurzen-type plates or mesh
A double hull of cast steel
An extra layer of Zimmerit
An anti-magnetic rubber lining
Unlike open tank destroyers like the Marder, tanks like the Panzer IV added Schurzen to reinforce their flanks.
9 / 10
Besides anti-aircraft fire and interceptor fighters, what other cause explained a large share of aircraft losses?
Mechanical failures and accidents in takeoffs and long flights
Sabotage at the Mariana Islands bases
Collisions with Japanese incendiary balloons
Navigation errors due to lack of maps
Accidents and mechanical failures, especially during fully loaded takeoffs, caused as many losses as enemy action.
10 / 10
