-.- I was on the last wave, just a bunch of soldiers. Cool right? wrong. oh look a car, thats ok. Oh look a tank, oh well i have my own. Oh crap! 2 more tanks and still some enemy troops! Call out the zooka and get everyone out of the bunker but that mg and officer! Woah. where did the tanks/soldiers disappear to? Boom one tank down 2 to go. Wait a second they disappeared.. hm. just troops to clean up then..... 3 more tanks? Noo!! 15 soldiers along with it?? And a bike and a car??? BLOW THEM UP WITH AN ARTY STRIKE! oh shit! johnson, jackson and smith run!!... boom! ****! just an mg, tank and zooka? damn it.. well i still stand a slight chance.. our tanks down! NO!! get our sig to call in another arty! "hes dead!" call in a new one! no points?? Booom! bunkers gone! all troops are dead except for the frenchie and hes pinned down and about to be obliterated by tanks! call in more frenchies! Boom! Fail.
Getting a machine gun early lets it level very nicely, gets 100 xp quick. My mg and sniper are killing every wave that comes at them. The gun flys left and right shooting everything and killing a good deal, sniper finishes it off.
My strategy(may have posted before):Get a machine gun! DO IT! Then get an officer. Your mg should get all boxes if possible if needed a medic is next otherwise get an engineer. If you are in a wooded area put a bunker in a light defense area to bulk it up. In open plains killing zone, I advise middle, its your choice however. Put mg in that bunker. Get snipers into a tree near the back. Mortars should be on rock/tree near middle to avoid friendly fire. Do what you wish.
The best way to survive is to pick which ones you are going to keep, and let the rest die if you are running low on missiles/picked ones getting attacked
