The ShadowVeil-class cloaked assault vehicle was a type of transport used by the Romulan Star Empire in the late 23rd century.
Built on an APC chassis and combined with tank grade armor, these vehicles were a suitable strike vehicle. This was enhanced even further by the addition of a Cloaking device. Despite these introductions, the ShadowVeil is actually a failing design that was effectively retired, however, certain Romulan commanders could produce the craft for their colonies should they wish to do so.
The reason for the designs failure is because of the vehicles incapability of using its Disruptor turrets in conjunction with the cloak, which was the original intention. Thus, the craft is forced to disengage its cloak before striking and makes it vulnerable for enemy attacks. Its strong armor, shield and weaponry still makes it a valid design which is the only reason why it is still produced in limited quantities. (TOS video game: New Worlds)
