Can anybody explain why people keep repeating that ost has the best team weapons? I don't get that.
Because, as you can read on this site:
https://coh2db.com/stats/
They have the best stats and in their given role they all perform as #1 without contest.
If you carefully check their tech, you'll also notice they have best availability of them compared only to UKF, but UKF got inferior vet abilities and stats on 2 out of 3 support units.
