So here we can discuss the flow.

On the first turn after deploy we had a wonderfull scene: B-S-B-S. B surrounded my small country and I surrounded his med. I risked to take an offensive approach and bougnt 8 tanks while B took the typical variant: short+long range.

It would have been very bad for me if he decided to press on my small country while defending the other flank of his med one as in that winter scenario , but he decided to invade the neutral country with only one light 4HP vehicle???? Why? The result as follows: guerlia, 4HP destroyed, revenue got at the end of turn and his med country is invaded from 2 sides. Now he has to fight 3 to 2 (getting revenue only from small country).

.... I wish I could post a screenshoT!

waiting for his next turn...

first game against a human
dont laught

dont how to comment my turn
you can that for me

Sorry, I'm not laughing just forgot how was it in mine first game

So the Next turns situation: S-B-S-B-S

B: For some reason S forgot to buy recruitments in his new country that left his border open. There will be no second gurellia there so I'm free to move into and prevent income. 2 LAVS 1 Mortar there, I destroy 1 LAV, 3 points of damage left. That means S won't be able to destroy my only LAV on his territory and I don't want haevy units to be fired upon. I also need to help my med ally, so lets invade his middle country. Hope I'll be able to defend the medium one untill help arrives (capturing S small ally will give 8$indemnity+2$inclome = 10$ on the turn of capture - enough to turn the tide of the battle)

S: Stupid me! Forgot to buy reinforcements! and short 1 damage to destroy that LAV!!! Wow, a neihboring country has gurellia. So I buy a Mortar, place it on the border - that gives me that extra 1 dmg to destroy enemy LAV (Here I used a gift of gurelia to help the other country, sacrificing the other- the good thing is that gurellia can move and fire immidiatly after deploy).
Have to make a remark: B did everyting well, both movement and firing while defending against tanks. (Tip: press onto my country, if you capture it - you'll get a help of 10). But there is a Guard Tower - don't like it: while it has a long range it still costs you 4$ and have only 2 dmg: I prefer to buy one HeavyBot with 3dmg, for 4$ - it has an extra dmg, 2 hp less, but it can MOVE! and if you wish some cannon fodder - LAVs are ideal - 4 hp for 1$.

So now: my left ally restored his border with the help of partisans from Nalivania, Nalivania is having hard times and Morda is being invaded from Nova Polska with 3,2 tanks and 1 Mortar. (Tip: You can reassign fire any time to get the optimal distribution, try to make a kill- a unit with 1hp still fires back, try to destroy more expensive units and balance the need to score a kill with the need to destroy expensive ones)

Another turn of this game (1 missed) turn 4

Some tips:
Strategy:
B: you'd disclose that SA 1 turn earlier - I can block you forces from below for 10 turns (while I have income). And even now you tanks and Step Bots are stuck in the woods. Better deployment in that situation would have been: Transport, 3 tanks, or Transport, 2 tanks + 2 scouts.

Tactics: that Anihilator has an extra range - thought you simply missed that Mortar. Be carefull not to let me have Nalivania back.
