ATGM tend to be
expensive items. Especially modern ones with added "special sauce" features like multiple charge warheads or top attack.
Me, if an OOB has a choice between an MBT with and without those cannon-launched ATGM then I usually plonk for the ones with (say) 6 more cannon rounds as they are far cheaper. Even taking the Close sSupport version if there is a C/S tank variant.
I prefer to have ATGM on a separate platform doing overwatch in a support vehicle type manner. If I
have to use the cannon launched ATGM variants of MBT then I usually
switch that weapon line off so I can manually fire the things at what
I determine is a valid target - not letting them pop them off in random opfire on some little tin can that wanders into LOS.
So, personally not a fan of MBT - or even light tanks - like say the M60A2 "Starship" and the M551 Sheridan in the 70s with ATGM as a primary
or secondary AT round. If I could have those 2 with
all HEAT ammo (and HE too - bigger bangs are better bangs!!) then I would be a happy bunny
