More details here:
The 4th Paras Battalion didn't see any action against the Soviets. When Romania concluded an armistice with the Allies on 23 August 1944, it was one of the few combat units around Bucharest that were available to protect the capital against the Germans, who attacked almost immediately. It saw heavy combat (used as regular infantry) and performed well, even against elite German units such as the Brandemburg commandos. Its heaviest losses came from a friendly fire incident, when an USAAF raid intended to hit the Germans bombed their positions instead. The unit was later disbanded, along with many other of the elite Romanian units, at the request of the Soviets.
It is possible that other smaller Romanian para units, which were used as airfield security troops, were the ones that repulsed several commando attacks of the Brandemburgers directed against Romanian airfields after 23 August (the purpose of these raids was to destroy the German planes in Romanian service).
