Yup, assuming ET1 is the Langfords Marine role ground specialists. 
100 of the Corvus Royal Manticore Marines
Just under 300 of Halo troops and regular humanness soldiers. 
Not sure how many Warspite carries but crew is 3.5K so can least say based on Google extrapolation a good 150 to 200 range given the sheer numbers and show. 4 platoons plus a HQ element. Raptor can drop 8 off with kit so not all can go anywhere. 

550 ish ground or boarding troops but only thr Langford has specialist anti replicator guns... so just shoot them till they die! 

And whatever anyone else has spare.

Agents.
Spartans.
And the power ranger team. 

Replicators beware!
