It builds a level 3 sentry with more health, rockets and ammo than a regular level 3 sentry.

At least I think that's what it does after looking through the code, I have been working a bazillion hours so I have not had time to work on this or play a game in a couple of years

Here are the amounts of Shells(Ammo), Rockets and Health for the various levels.

    // Max Sentry Ammo for Level:         mini,   1,   2,   3, max
    stock const TF2_MaxSentryShells[]  = { 150, 100, 120, 144,  255 };
    stock const TF2_MaxSentryRockets[] = {   0,   0,   0,  20,   63 };
    stock const TF2_SentryHealth[]     = { 100, 150, 180, 216, 8191 };
