M2TW have this feature and for this time frame seems a good thing. but on m2tw besides this really go rank by rank each time one rank fires they stand up and run to the last line wich wastes alot of firepower and for awhile leaves your line in a mess and exposed to enemy fire.
Not using this feature, will improve the firepower and keep stable your lines, some things will remains and kneeling to reload and such.
So i brought it to you , fire_by_rank or not? wich is con's and pro's of wich ?
