They are 15mm vehicles for my US forces, while they were also used a little by the British (and Commonwealth) they were not heavily used in Europe . But they did see action in the Pacific.
These have been VERY badly cast with bits missing and air bubbles and mold slips and just about everything wrong you can imagine. But they were cheap on eBay I think someone tried to start casting from another make and just did not know what they were doing. Ok Moan over, as I said they were cheap and for that I can forgive a lot. I will not use the seller again though. Americans being well American did give them between 2 and 4 machine guns which are not included. Also the MGs could be either .50 cal or .30 cal depending I think on the stock and how many were to be used. That does not matter.
In real life they could transport up to 28 men or a jeep or artillery piece or supplies or well just about anything from ship to shore. In PBI "Carriers" no matter how large can carry 4 infantry stands, so a squad, not a platoon. So an agreement needs to be made (which I have made) with normal players on using them. For me they will mostly be acting as troop deployment markers and not actual fighting vehicles. As PBI works in squares thy will (Temporarily) make the beach square Partial cover and allow troops to deploy in their square and the 1 on either side (Which will NOT get the cover bonus.)
Being just green with tracks and weathering they were an easy paint and both done and based and put away in an evening with no issues, complaints or squabbles. While not super useful they do round out the US amphibious capability in some WW2 games.
below is a Youtube clip of the LVT4 in action (from a film/TV series) just for those NOT familiar with the vehicle. And if anyone wants to know what to get me as a gift a real one would be most welcome. Colours and MG configuration could and were changed to suit the need
Or here is a real life on in a separate clip
