M4A3,M4A3 HVSS & M4A3-Firefly hybrid
Mostly retired US Army Variants, Both the Firelfly and M4A3E8 where tested during a trial for the lastest M4A3 upgrade. The QF 17-pounder gun was chosen because it performed better at jungle and plain environments when tested, but the engine of the Firefly did not proved the same, they choose the M4A3E8's engine and produced it with a License to handle the 17-pounder's weight. Latest update was Identified as "M4A3QF17" or simply as the "M4A3PH" but both designations are not official. 44 where in service in 1951 and 5 more was produced locally in 1953. Prominently used in the 1st Cavalry Squadron.
Obtained when the US fully retired M18 in service, about 20 where given by the Philippines. Used by the 10th Infantry (Steady…On) Battalion.
A mix between M7 Priest and M12 Gun Motor Carriage after they where both retired fro US service and some in Philippine service. Both where mixed and resulted in the creation of the A13 SPG, due to some units being nonfunctional due to terrain and design problems and lacking of parts to ease of use. Only 15 where Converted, and 3 where built from the scratch once the factories managing maintenance of M4's was able to produce 5 more M4A3PH's with the help of experienced US M4 engineers. Prominently used in the 1st Field Artillery Battalion.
