Jeeps
Okay, the jeep only has one purpose in my book, and that's to hunt down snipers. I once played against a player who was losing and knew it, but he also knew another thing, my entire army pretty much consisted of infantry units. And that's when he started spamming snipers. I noticed this and realized the "Unit Sniped" pop up wasn't going to save me. I did not say "JEEP SPAM TIME!!!" I instead got one jeep out, and hunted down exactly all 8 of his snipers. And you know what, after I finished all his snipers off, all he had left to answer my attack force on his base was one pioneer squad. From that experience, I realized that the jeep is a predator that turns the hunter, into the hunted. Do not use this unit to take on a pioneer squad, let alone a volks squad, this unit only has one purpose and one purpose only. Hunting down snipers.
Halftracks
This is one of my best friends when I play as the American faction. The reason being is that I no longer have to retreat my squads to reinforce, I can simply have my half track drive up there and boom. As soon as I can I get the Quad Mount .50 Cal upgrade for this vehicle, and if I think I can get away with it, I'll run this vehicle into the enemy's base and put some more money into pastors pockets. If you think the enemy has no anti tank weapons up and running, feel free to have this unit (with the upgrade) lead the way of your attack force. This unit however, does have it's downsides, it's very vulnerable to pioneers flamethrowers and all antitank weapons. If the enemy has antitank guns up and running, have your rifleman squads lead the way. And reinforce as needed.
M8 Armored car
I will only get this vehicle in certain conditions, if I think the enemy doesn't have any antitank units up, (and yes I know volks squads do have anti tank weapons but I know if I'm careful they won't hit me) and if I think they can run into the enemy's base and cause havoc. The second reason is if the enemy has a puma up without the upgrade. The reason I'll go for this unit to duel the puma instead of a anti-tank gun is because the puma is fast and can easily flank that anti-tank gun and take out the crew. You should get all the upgrades for this unit asap, starting with the armored skirts. A cool thing about this unit is this, if you see a stug coming up, you can try to drive up to it, and lay a mine right next to it, and drive off. Another great tool of this vehicle is that if you decide to do an all out M8 armored car attack on the enemies base, is that you can simple lay mines where you know enemy units will be coming out. Be careful when using this unit though seeing how it's very weak vs anything antitank related.
Anti Tank gun
Man oh man oh man, this is one of my best friends. When you get about 2-3 of these together, they really become a tank killing force. However this unit has great weaknesses. It can be flanked by pretty much any infantry squad and be taken out which is why you should keep a infantry unit up there with them. At times I am a bit hesitant to bring this out when the enemy spams pumas, a puma can easily flank this gun and take the entire crew out in a wink of an eye. So this gun is great for what it was made for, but don't expect it to be able to defend itself against infantry.
M10 Tank destroyer
This tank is great. It doesn't cost very much to buy, it can deliver a knockout punch, and it sure as hell should never be counted out when playing as Americans. However, like all units it has it's weaknesses. First off, it's terrible vs infantry, it has terrible armor when it comes to fighting tanks and antitank weapons, and man when it get's hit from the rear you have no idea if it's gonna make it. When using this tank, have it run along side Shermans, or rifleman, or anything that will help it if it runs into trouble. Just don't send this guy to fight pretty much anything by itself. There was one time for me however where this tank really saved my neck, the enemy had me cornered in my base, and I knew I wasn't going to be able to fight my way out of it, I did notice however that I had a lot of fuel, and enough manpower to call this tank out. So I called one out, and then another. And when I felt it was safe, I snuck these tanks out where the enemy wasn't attacking from. I snuck them all the way to the enemies base, and boom. As soon as those bad boys showed up in the enemy's base, all of the enemy units that were attacking retreated back to there base. I knew those tanks wouldn't stand a chance vs all of those units attacking, so I ran all my infantry units up there, and by then I had already lost one M10, but I set up all my infantry up, and started regaining the map and eventually called in a sherman, and took out their base. So yes, these tanks our weak, but boy do they help.
M4 Sherman Crocidile
Don't look to me on advice on how to use this tank, I rarely if ever call this tank out, if you can call it that. Well what can I say, it's decent vs weak infantry, and okay burning down buildings. It can be upgraded with a bulldozer that can create paths through trees and hedgerows, don't try to fight anything antitanks related with this tank and you will be fine.
M4 Sherman
First off, when you get this tank out, do not get cocky. Don't try to be rambo and rush the enemy. I've seen to many new players lose this tank because they thought it could beat anything. Well here's the truth,
it can't. When using this tank be careful, I usually keep this in the rear away from the action and only call it up if I need it. Don't even dream about calling this tank out without the better gun upgrade that can be purchased from the tank depot. This tank can be upgraded with a machine gun and a minesweeper which can be useful if the enemy has mined the road. Don't attack with just one unless you know the enemy has little to nothing to fight back against it with. Whenever I do an attack with these guys, I try to do it with at least 3 of them. When you do this, you have a better chance of beating that panther, or panzer 4. Or one of those shots killing a pak38 crew. This tank in my opinion should be your base of tanks, but when waiting to buy one, do not let your manpower grow to where you can swim in it. Sure you're waiting for that 90 fuel, but for god's sake get something out with that manpower.
