...why exactly would you need 3-4 of them to attack on HMG in a building?
To get that Inc nade inside there. Same as US against MG42 you need at least 3 rifles to bumrush and nade it.
Smoke and flank. You got the smoke barrage for the LeiG.
The state what leig is now i don't think that half of the players can micro it at a state that you would get the 1 vet to have that smoke.
