Lepty once over 6 men (all units: infantry, mechanized, statics) in squad you get like a x6 chance per second for an airstrike or artillery barrage to trigger. And believe me, airstrikes and arty barages f*ck up your whole game.
Further tips: For going late game (wave 150+) dont focus all tp's in anti infantry (Theres not a very big chance you get a tank or high armored killer before wave 50). And another tip is that theres more than just units to buy with tp.
Lol i finnaly got up AAA and sum ground units with threnches when an enemy flak spawns, i think ok my AAA will shred that thing apart, next wave 2 PAK AT's litterly in eachother and an unfair event that drops a bomb on my best shooters trench blowing them all up, HQ decides to resupply the germans giving them an extra flak and 2 motorcycles + an officer and a mortar. Mortar blows up other trench, paks blow up AAA, and my medic i just hired is sitting there with 100 germans coming at him, ****
After 12 tries you finnaly got up your AAA and your tank + 4 soldiers with 70+ rifle and spec op with 90 rifle. And guess what mr german artillery was thinking. Hey lets bomb it.
ok i know youre not supposed to go ez on us but a WESPE blitz wave on wave 33 followed by an extra wasp and a tiger + 2 flaks on wave 33 and 34. Bro calm
holy fuc found a glitch : when yu call in cas or any air support that doestn imeediatly take yur tp you can spend that tp and still get the air support
