Here is the current status of Grenades left in the Platoon:

1st Squad
Simovic = 7 (used 1)
Brown = 15 (used 1)
Quinn = 15 (used 1)
O'Brien = 1 (used 3)

2nd Squad
Kurosaki = 0
Morse = 4
Lionmane= 8

Support Squad
Sheppard = 12

Note. Some Marines didn't have enough combat weight to carry any grenades (Kurosaki) or others only had the ones that come pre-loaded in their Pulse Rifle (O'Brien).

Cheers for the info Dugan, I was not too sure if I was carrying 8.

No that'd have put you over encumbered. You can check your characters gear by going to the Character Upload section.
