I do it, but only on a handful of maps (Wanda, SEagle) as when I have 3 other infantry and an APC crew the infantry often has more survivability. My favorite tactic is to rush an objective, drop off the infantry, and tell the APC to do a once around the block so we can ensure there are no AT threats.Simple: Because no one does it.
When the APC has a large cannon and thermals, its the other way around with the infantry supporting the APC.
No while you may be right in saying it has more survivability, it would be much better off working in the light tank method that will, quite simply, kill more of them than us, by using the 'tickets as opposed to objectives' mindset.
Statistics don't work here, plus with the spontaneity and randomness of combat in PR (majority thanks to the no realistic fear of death) AT operators will usually sacrifice their lives to destroy an asset.If you use Infantry & the APC together the APC WILL survive 9/10 times, get on mumble so you can communicate, & roll up together, if you see an RPG/LAT shout it out & everyone will open up on the target & the LAT will miss (Or in a rare case on Muttrah... shot at the wrong APC & blow it up... *facepalm*).
