Recently some AH4 howitzers (25-40 km range) in use by the RSF (Rapid Support Forces) in the ongoing siege of El Fasher have been documented somewhere northeast of El Fasher city, the howitzers clearly are near a river bank (many such river banks NE of the city as seen in pic 2). For reference, the first satellite photo out of the three in pic 1 is what the location would most likely appear as on Google Maps.
