Tbh it saved me more than couple times against autocannons so I prefer to keep it, not to mention ERA itself can cause overlapping and plus extra 50 cal is bonus in my book.
In the end its all about personal preference whether you keep TUSK kit or not so I’m not oppose any idea in this case.
Actually it does a lot, especially against 30MM APDS and APFSDS, combining with composite side skirt it makes you almost immune from 90 degree side shot and any angle completely renders those cannons useless.
As for the mobility it doesnt decrease that much, sure you will still feel it but Abrams still faster than 12.7 Leo2’s and can keep up with other top tier tanks even with TUSK kit most of the time.
Only for trolling the enemies, when hull down you can expose only the mg to the enemy who already pre-aim at your direction, switch to mg control then destroy his tracks and place a marker on his head. T29 also can do this over the containers in cargo port lol
Glad to know that I ain’t the only annoying ass player to deal with lol the recently added russian sausage ifv with an atgm launcher held by a 20 foot pole is extremely good at using tricks like this. You might get a little bit more firing angle if you raise the suspension on the 1128.
