First is the M17 the fourth is the LCT55 or Long Cannon Tank 55 during the battle for Zinam fields both tanks come from Falcoria M17 in 1947 and LCT55 in 1959 

The LCT55 has a more longer cannon and fixed a problem whit the M17 it dident have a front machine gun and the one up in the roof was too risky for the commander and couldent see outside from the hatchet causing a lot of tank losses and the crew of fourth people meanwhile the LCT55 has fifth people inside one driver,one machine gunner,one gunner,one loader and the commander and whit the front machine gun the infantery ambushes lowerd but still the sides and back are the most dangerous zones, also they have tools for emerency situations and are good straped into the tank making sure the enemy dosent rob them or fall off

The communist people republic of Baravia is a coummunist country in expantion and they found their next target Falcoria. Tinking in a easy win the Baravian commanders and generals dident tink much about their strategy since they where blinded by their proud and greed from pass victories in a outdated tactic of mass assault whit infantery but in the 6 of april of 1962 Baravia atacked by surprise Falcoria but they where atent and put divisions close to the border in case of an atack making a good defence in a more fouced mecanized tactic making Baravia have dificulties in the first day and after 1 week the goverment was trying to silent information about their losses to the public

The Oriental Federation of Falcoria is a federation goverment in a long peace since the civil war in 1929 between the goverment vs communist vs some other smaller factions no one dident care after the civil war ended and enterd in a reboulding state and when finally the economy was having a boom in the market they designed the M17 in 1945 but it was just an idea and in 1947 was a real tank it worked but not having a front machine gun was its biggest flaw fixed whit the LCT55 in 1959 when they realize Baravia expansionism was getting closer they secretly moved some of their divisions close to the border waiting if Baravia would really fall and they did it something the entire population laughted

The battle of the Zinam fields was a long painful 1 month battle for Baravia losing aporx 25.000 soldiers, 80 tanks, 120 mecanized vehicles and 200 trucks,cars or supply vehicles meanwhile Falcoria lossed 10.000 soldiers aporx,100 tanks (mostly M17),50 mecanized vehicles (protected by tanks in case of a more heavier enemy), 150 trucks,cars or supply vehicles

The two pictures of the map the "official" dosent convince me much so i ask you what is better the "official" or the scrapped one?
