*68 HASELTON, P.J.
Defendant pleaded guilty to unlawful use of a weapon, ORS 166.220, a Class C felony, and, pursuant to stipulation, was sentenced under gridblock 9C on the sentencing guidelines to a downward departure sentence of probation. Shortly thereafter, defendant's probation was revoked due to his violation of the general condition of probation that he obey all laws. Upon revocation of probation, the court sentenced defendant to 60 months' imprisonment  a presumptive sentence under gridblock 9C  and also ordered defendant to serve 36 months of post-prison supervision. Defendant did not object to that disposition. On appeal, defendant challenges the lawfulness of the post-prison supervision term. The state concedes that the post-prison supervision term is plainly erroneous and agrees with defendant that the case should be remanded for resentencing. As explained below, we conclude that the state's concession is well-founded and exercise our discretion to correct the error.
Because defendant was convicted of a Class C felony, the maximum sentence, including post-prison supervision, is five years. ORS 161.605(3). We have previously treated identical errors as apparent on the face of the record. See, e.g., State v. Angell, 200 Or.App. 244, 113 P.3d 988 (2005).
The question remains whether we should exercise our discretion, under Ailes v. Portland Meadows, Inc., 312 Or. 376, 823 P.2d 956 (1991), to address that unpreserved claim of error. See, e.g., State v. Jury, 185 Or.App. 132, 138, 57 P.3d 970 (2002), rev. den., 335 Or. 504, 72 P.3d 636 (2003) (reiterating that, under Ailes, the determination of whether a claim of error satisfies the requirements of "plain error" is merely the first step in a "two-step process"). That determination involves the assessment of a variety of factors, including the following:
"[T]he competing interests of the parties; the nature of the case; the gravity of the error; the ends of justice in the particular case; how the error came to the court's attention; and whether the policies behind the general rule requiring preservation of error have been served in the case in another way, i.e., whether the trial court was, in some manner, presented with both sides of the issue and given an opportunity to correct any error."
Ailes, 312 Or. at 382 n. 6, 823 P.2d 956. Recently, in State v. Fults, 343 Or. 515, 173 P.3d 822 (2007), and State v. Ramirez, 343 Or. 505, 173 P.3d 817 (2007), the Supreme Court admonished that Ailes discretion is to be exercised sparingly and reiterated that any correction of unpreserved error must be fully and carefully justified.
We exercise our Ailes discretion in this case because of the following compelling combination of circumstances:
First, with respect to "the competing interests of the parties," Ailes, 312 Or. at 382 n. 6, 823 P.2d 956, there are no such "competing interests" with respect to the correction of the error in this case. (Emphasis added.) Rather, unlike in Fults and Ramirez, the state agrees here that the error should be corrected. Thus, the parties' interests in correction, if not necessarily congruent, do not conflict.
Second, given the circumstances presented here, where defendant was convicted of a single crime and the revocation of probation went only to that crime, there appears to be no possible "strategic" or "tactical" reason for defendant's failure to have raised this objection before the trial court. Accord Fults, 343 Or. at 520, 173 P.3d 822 (noting that "there is a significant possibility that defendant's failure to object was in fact a strategic choice" (emphasis in original)). This is not a case, for example, where, if defendant had timely objected, other, potentially disadvantageous consequences with respect to the configuration of the entire sentence might have resulted. Id.
Third, in a related sense, there is no way that the trial court could have imposed  or, on remand, can impose  the same sentence albeit through a different means. Given the limitation in ORS 161.605(3), the only lawful sentence that can be imposed is considerably shorter than the one that the court did impose. Thus, a remand here does not implicate "the interest of the judicial system in avoiding unnecessary repetitive sentencing *69 proceedings[.]" Fults, 343 Or. at 523, 173 P.3d 822.
Fourth, there is no suggestion here that defendant may have "encourage[d] * * * the judge's choice." Id.
Fifth, the "gravity of the error," Ailes, 312 Or. at 382 n. 6, 823 P.2d 956  the imposition of a sentence three years greater than the statutorily prescribed maximum  is substantial.
Remanded for resentencing; otherwise affirmed.
