Front line cannon fodder
Well, there is that one statement about him taking everything the army could throw at him, or something along those lines. But it's too vague IMO. Even if we take it to the extreme and assume they included nukes, we still don't have enough to go on. For example, if Homelander did survive a nuke, what was the yield? Was it a direct hit or just a nearby impact? Was he totally fine or incapacitated to some degree? Without info like that the statement is basically worthless other than sounding cool.
In terms of onscreen feats, he had that portion of tunnel and stuff collapse on him which he survived, but it took him several minutes to get free. And, again, we don't see what happens to him. He could have been KO'd, woke up 5 minutes later and immediately busted free. Or he could have been conscious throughout but taken the entire time period to free himself. Either way, not exactly the best showing for him.
IIRC, the only punches we've seen him take from another super was from Stormfront, but she's nowhere near as strong as Will is.
On a somewhat related note, that lifting feat from Will is also a durability feat. Because his body needs to be both strong enough to perform the feat and tough enough to do so without injuring himself. Like it's pointless if your muscles are strong enough to do something but your bones, joints, ligaments etc. shatter or tear apart when you do it.
