I was curious about everyone's unlock progress. I'll try to set a standard to follow.
If you go to the battlelog Overview, you can quickly see bars for each kit progress, under service stars. I approximate the progress. [Note the play button underneath, for fun give that a press]
10% Assault
100% Engineer
90% Recon
70% Support
15% Commander
For weapons, I went to the Unlocks then Weapons tab. Numbers include the default. You can see the total number on the right in the black bar of the weapon types, such as "Assault Rifles 3/11".
3 of 11 Assault
6 of 10 Carbines
1 of 8 Shotguns
5 of 9 LMGs
2 of 9 PDWs
2 of 8 DMRs
1 of 9 Snipers
2 of 13 Hand Guns
4 of 7 Grenades
4 of 9 Knives
For vehicles, similar to weapons, Unlocks then Vehicles tab. It shows the progress numbers on the same line as the category.

0 of 12 Attack Jet
0 of 12 Attack Heli
