Various weapons were fitted inclusding 37mm BK 3.7 and 75mm BK 7.5. An interesting weapon was a battery of six 75mm smoothbore recoiless rifles that fired downawrds and to the rear. This system was fired by an automatic magnetic trigger that fired when the aircraft flew over metal objects. This system was reported to be quite successful.
While performance was slow and maneuverability was pretty bad, it was pretty well armored and having two engines is a nice feature for a ground attack aircraft. Its small size and "compact" (read "cramped and claustrophobic") layout also make it harder to hit. Supposedly.
Mostly used in the NA/Med Theater and on the Eastern Front. Heavily used by Romania both beside and against the Germans.
