How do I get ALT+F movement to work in Red Alert Remastered?

Team Movement at Slowest Unit Speed (Red Alert only)

I'm assuming it means that a selected group of units with advance at the speed of the slowest unit. I also assume this means a team can travel as one and maintain formation.

But when I select a group, press ALT+F and then choose a destination, everyone still moves at their own speed. I don't want vehicles to go ahead of the pack and die before the slower infantry and other units make it to the location.

Am I using ALT+F the wrong way? When am I supposed to press it? Do it move first and then press it? Or do I press and then choose the location?

Red Alert doesn't give any kind of alert, message, or indication of anything when ALT+F is pressed. So I don't even know if it works (like Guard Mode with G key which doesn't give any feedback either).

Did you assign a team number to the group? If you give them team number 1 for example and issues the team formation, the indication that the group is on the slowest unit speed is 1F appearing on them when you select them. I think you need to assign a team number first. They will move on the same speed as the slowest in the group. It works for me.

Well, that's rare for me to use.
If you have 2 or 3 teams, main tank team, and 2 3 as support, then this will be useful I guess.
Like Aftermath, some mod's AI will use Shock trooper, light tank is weak against shock trooper, so Artillery and Rangers will be useful to deal shock trooper, but you want your artillery and rangers keep safe distance, I think Alt+F will be useful.
Or Soviet using Shock trooper+infantry, Tesla tank and V2 rocket, you'll need shock trooper and infantry protect Tesla tank and V2 rocket, with this so you can focus on controlling heavy tanks, and let your support team push safe.
