That is true, their "Turrents" are simply light, Pintle guns. (Rules available in the CS download under the Behind the Crimson Veil).
Basically they do a single block of damage, tough to hit with (Must succeed in the TH roll by +4). Not really usefull but good for character purposes
A pintle gun is basically a .30 caliber light machine gun. Instead of a 250 round belted gun, it is like a BAR with a 20 round magazine, or a Bren with a 30 round magazine. In addition the rounds are probably standard rifle weight instead of anti-aircraft (Not AP, probably 150 grain weight VS 187-200).
All of which WK seemed not to take into account when they made thier games. The rear guns on Firebrands and Kestrels do a good lick of damage.
I always thought they should do more damage. But it is sorta nice having a pintle gun like that.
Although on my personal kestrals,etc. I replaced it with a single .30 waist-mounted gun.
The pental guns on Stukas and SBD's didn't do much good.
Yeah, but I always thought that in the world of CS when stuff has been hard-tested for so much longer, it would be better. (For example having better rear-facing firepower,etc,etc.).
The problem with that is the biger the bore, the biger the recoil. And simple little pintle mounts can only take so much foerce before they break. Also the gunner'd have a harder time dealing with the aiming due to kickback. Plus the weight would slow him down in following a target.
